It should be understood that the drawings in the present application only serve the purpose of explanation and description and are not used to limit the scope of protection of the present application.

Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.
[0038] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.
[0039] For the design of some games, the game's art style may be a unique block style. In order to match this special style, the production of model special effects in this type of game is different from the conventional 3D model production process. They are all made using exclusive software BlockBench (a 3D modeling tool with outstanding functions). However, since BlockBench is not a model software widely used in the industry, it has certain limitations in function. It can only produce rigid body special effects of the model, but cannot complete the production of soft body special effects, resulting in limited production of model animation and poor animation effects.
[0040] Based on this, this solution provides a model animation processing method, which can make a model in BlockBench software, and add or mount model parts with special materials or special effects as needed, split the model to obtain at least one sub-model, and convert each sub-model obtained by splitting into FBX (Filmbox, 3D file format) format and import it into 3Dmax (3D StudioMax, 3D modeling, animation and rendering software), add wiring to the sub-model and split the model in 3Dmax, so that the sub-model has editability and deformability. Based on the split sub-model, the corresponding flexible animation effects of the sub-model can be generated in 3Dmax; and the rigid animation effects of the model are produced in BlockBench software. Finally, the rigid animation effects produced in BlockBench software and the flexible animation effects produced in 3Dmax are imported into MC (an auxiliary tool that can edit Minecraft game module content, modify game data or create game worlds) compiler. By making hanging points between the sub-model and the model, the flexible animation effects of the sub-model are added to the model to generate the target animation effects of the model, so that the model realizes both rigid animation effects and flexible animation effects, enriching the animation effects of the model.
[0041] Figure 1 A flow chart of a model animation processing method provided in an embodiment of the present application; the execution subject of the method can be a computer device such as a terminal device, a server, etc., such as Figure 1 As shown, the method may include:
[0042] S101. Split the model according to information of a part of the model where special effects are to be generated, to obtain at least one sub-model.
[0043] A model can be obtained by meshing in BlockBench. In this embodiment, the model obtained can be a character model. There are usually some parts in the character model. By adding special effects to these parts, the display effect and authenticity of the model can be improved. Based on the animation effect to be achieved, the parts of the model that need to generate special effects can be determined in advance, so that based on the information of these parts, the model can be split to obtain at least one sub-model.
[0044] Among them, the sub-model is the part that needs to add special materials or special effects; for example, the sub-model can be the head or cloak of the model.
[0045] S102 . According to the target flexible animation special effects corresponding to each sub-model, wiring is added to each sub-model, and based on the added wiring, each sub-model is segmented to obtain each segmented sub-model.
[0046] After splitting the model in BlockBench to obtain at least one sub-model, the model data of the sub-model can be imported into 3Dmax software in FBX file format. In 3Dmax, a sub-model is first generated based on the model data of the imported sub-model.
[0047] In some embodiments, the split sub-models all need to produce flexible animation effects. For example, for the head sub-model, it is necessary to produce the fluttering effect of the hair; for the cloak sub-model, it is necessary to produce the fluttering effect of the cloak.
[0048] Since the sub-models imported into the 3Dmax software are all rigid models without editing features, for example, the cloak sub-model may be a cube model. There is no line segment information in the cube model, and actions such as folding and bending cannot be achieved.
[0049] Therefore, the number of segments of the sub-model can be modified and wiring can be added in the 3Dmax software, so that the sub-model can be edited and deformed.
[0050] Based on the added wiring, the model can be segmented. Usually, the segmentation of the model is based on the wiring, and the model is separated from the wiring to generate a new model surface in the sub-model based on the original sub-model. Here, the sub-model segmentation does not mean dividing the sub-model into multiple parts that are completely unconnected, but separating the model from the wiring, and connecting the two separated parts through the skeleton points at the wiring, so that the segmented sub-model can be bent and folded at the wiring.
[0051] It is worth noting that the position of the wiring added to the sub-model and the split position when the sub-model is split based on the wiring can be based on the target flexible animation effect corresponding to the sub-model. The target flexible animation effect refers to the flexible animation effect that you want to add to the sub-model.
[0052] S103 . Determine the first animation data of each skeleton point in each segmented sub-model in each frame according to the target flexible animation special effect corresponding to each sub-model.
[0053] In some embodiments, the target flexible animation effects to be added to each sub-model can be pre-designed. For example, if you want the cloak sub-model to achieve the effect of freely floating in the wind, you can pre-design the animation of the cloak floating in the wind. Based on the designed animation and the defined animation key frames, the first animation data of each bone point in the cloak sub-model under each key frame can be determined. Here, each frame can refer to each pre-defined key frame. The first animation data can refer to the flexible animation data corresponding to each bone point. The first animation data can include information such as the position and rotation direction of the bone point.
[0054] It is worth mentioning that the sub-model after segmentation is still a model, but compared with the model before segmentation, the sub-model after segmentation has more editable faces and editable bone points.
[0055] S104: Generate flexible animation effects for each sub-model according to the first animation data of each skeleton point in each frame in each segmented sub-model.
[0056] According to the first animation data of each bone point in each sub-model after segmentation in each frame, the display position and direction of each bone point in each sub-model can be controlled, so that the flexible animation image of each sub-model in each frame can be rendered. The flexible animation image in each frame is a static image, and by continuously rendering and outputting the flexible animation image in each frame, the flexible animation special effects of each sub-model can be generated.
[0057] S105 . Generate target animation effects of the model according to the flexible animation effects of each sub-model.
[0058] In some embodiments, the flexible animation effects of each sub-model produced in 3Dmax can be imported into the MC editor, and the MC editor can produce model hanging points to add the flexible animation effects of each sub-model to the model to generate the target animation effects of the model.
[0059] In another feasible method, after generating the first animation data of each bone point in each sub-model in each frame in 3Dmax, the first animation data of each bone point in each sub-model in each frame can be directly imported into the MC editor, and the MC editor generates flexible animation effects for each sub-model and completes the addition of flexible animation effects based on the first animation data of each bone point in each frame in each sub-model.
[0060] In summary, the model animation processing method provided in this embodiment includes: splitting the model according to information of the part of the model where special effects are to be generated, so as to obtain at least one sub-model; adding wiring to each sub-model according to the target flexible animation special effects corresponding to each sub-model and segmenting each sub-model based on the added wiring to obtain each segmented sub-model; determining the first animation data of each bone point in each segmented sub-model in each frame according to the target flexible animation special effects corresponding to each sub-model; generating flexible animation special effects for each sub-model according to the first animation data of each bone point in each segmented sub-model in each frame; generating the target animation special effects of the model according to the flexible animation special effects of each sub-model. This method splits the model based on the information of the part where special effects are to be generated. For the sub-models obtained by the splitting, based on the special effects animation to be generated, wiring is added to the sub-models and the sub-models are separated, and editable bone points are added in the sub-models to make the sub-models editable and deformable. Based on the target flexible animation special effects corresponding to the sub-models, the flexible special effects animation of the sub-model can be generated, and the flexible special effects animation of the sub-model is added to the corresponding position in the model to generate the target animation special effects of the model. Through this method, the limitations of the production of flexible animation special effects in some games can be solved, the effects of model animation special effects can be improved, and the display effects and authenticity of the model can be enriched.
[0061] Figure 2 A flowchart of another model animation processing method provided in an embodiment of the present application; optionally, the method of the present application may further include:
[0062] S201. Determine second animation data of each skeleton point in the model in each frame according to the target rigid animation image of the model in each frame.
[0063] In some embodiments, the basic movements of the character are all realized through rigid animation, such as walking, punching, jumping, etc. Therefore, it is also necessary to produce rigid animation effects of the model.
[0064] Optionally, the creation of rigid animations of the model can be implemented in BlockBench.
[0065] Optionally, the model can be placed in a scene, and based on the set rigid animation to be achieved, the rigid movements of the model in each frame can be shaped frame by frame, and the target rigid animation image in each frame can be captured. This is similar to pulling and adjusting the corresponding bone points in the model to transform based on a known rigid animation, so that the model switches from the previous action in the rigid animation to the next action, and in each action, a frame of rigid animation image can be captured.
[0066] Based on the target rigid animation image of the model in each frame, the second animation data of each skeleton point in the model in each frame can be calculated, and the second animation data represents the rigid animation data of each skeleton point in the model.
[0067] S202: Generate a rigid animation effect of the model according to the second animation data of each skeleton point in the model in each frame.
[0068] In some embodiments, similar to the above-mentioned process of generating flexible animation effects, based on the premise that the second animation data of each bone in each frame is known, the position and rotation direction of each bone point in the model in each frame can be determined, thereby rendering and generating a rigid animation image of the model in each frame. By continuously outputting and displaying multiple frames of rigid animation images, the rigid animation effects of the model can be obtained.
[0069] Optionally, in step S105, generating the animation effects of the model according to the flexible animation effects corresponding to each sub-model may include: generating the target animation effects of the model according to the flexible animation effects of each sub-model and the rigid animation effects of the model.
[0070] The flexible animation effects of each sub-model and the rigid animation effects of the model can be imported into the MC editor together, and the MC editor generates the target animation effects of the model based on the flexible animation effects of each sub-model and the rigid animation effects of the model. The target animation effects generated in this embodiment include both flexible animation effects and rigid animation effects, enriching the animation display effect of the model.
[0071] Figure 3 A flowchart of another model animation processing method provided by an embodiment of the present application; optionally, in step S102, according to the target flexible animation effect corresponding to each sub-model, wiring is added to each sub-model and based on the added wiring, each sub-model is segmented to obtain each segmented sub-model, which may include:
[0072] S301 : Determine the position of the wiring to be added according to the model structure of the sub-model and the movement direction of the target flexible animation effect corresponding to the sub-model.
[0073] In some embodiments, the position of the wiring to be added can be determined based on the model structure of the sub-model itself and the movement direction of the target flexible animation effect to be generated by the sub-model, that is, the animation schematic direction, combined with experience.
[0074] S302 . Add wiring to the sub-model according to the location of the wiring to be added.
[0075] Based on the determined wiring position, wiring can be added at the corresponding position of the sub-model.
[0076] For example, assuming that the sub-model is a hexahedron composed of points, lines and planes, adding wiring means adding a circular line segment at the corresponding position on the hexahedron. Assuming that the sub-model is an arm, in order to make the arm bendable, a circular line segment can be drawn along the circumference of the elbow.
[0077] S303 , according to the target flexible animation effect and based on the added wiring, the sub-model is segmented to obtain the segmented sub-model.
[0078] It is worth noting that there may be multiple added wirings, but not every wiring may be used. Based on the target flexible animation effect to be achieved, it can be determined based on which wirings to segment the sub-model, thereby segmenting the model from the determined wirings.
[0079] It is similar to dividing a whole train into multiple carriages through wiring, so that each carriage can be bent. If the train is not divided, the train as a whole can only perform rigid movement and cannot achieve flexible movement.
[0080] Figure 4 A wiring diagram provided in an embodiment of the present application, Figure 4 Taking the cloak sub-model in the model as an example, the line segments shown in the cloak are the results of wiring.
[0081] It is worth mentioning that, considering the problem that the model may be incomplete or disappear when loading the model in the MC editor, when the sub-model split in BlockBench is imported into 3Dmax, a copy of the original model will be retained in BlockBench, that is, the original model made by BlockBench will be retained. After the sub-model is imported into 3Dmax, a proportionally enlarged sub-model can be made in 3Dmax for subsequent processing. The original model retained in BlockBench is used as a reserve display model.
[0082] Figure 5A flowchart of another model animation processing method provided by an embodiment of the present application; Optionally, in step S103, according to the target flexible animation effect corresponding to each sub-model, determining the first animation data of each bone point in each sub-model after segmentation in each frame may include:
[0083] S501 . Determine a flexible animation image of the sub-model in each frame according to a target flexible animation effect corresponding to the sub-model.
[0084] In one feasible solution, according to the target flexible animation special effect corresponding to the sub-model, the flexible animation image of the sub-model in each frame can be extracted from the target flexible animation special effect. For example, during the playback of the target flexible animation special effect, the flexible animation image of the sub-model in each frame can be obtained by shooting images frame by frame.
[0085] S502: Determine first animation data of each skeleton point in each frame in the segmented sub-model according to the flexible animation image in each frame.
[0086] According to the flexible animation image in each frame, the position, rotation direction and other data of each bone point in the segmented sub-model in each frame can be determined, and the position, rotation direction and other data of each bone point in the sub-model in each frame can be used as the first animation data of each bone point in the segmented sub-model in each frame.
[0087] Figure 6 A flowchart of another model animation processing method provided by an embodiment of the present application; optionally, in step S105, generating a target animation effect of the model according to the flexible animation effects of each sub-model may include:
[0088] S601. Determine a plurality of connecting bone points between each sub-model and the model according to the connection relationship between each sub-model and the model.
[0089] In the MC editor, the MC editor determines multiple attachment bone points between each sub-model and the model according to the connection relationship between each sub-model and the model. The attachment bone point refers to the bone point at the part where the sub-model is directly connected to the model.
[0090] For example, assuming that the sub-model is a cloak model, the cloak model is usually directly connected to the shoulder part of the model, so the direct connection point between the cloak model and the shoulder part of the model's body can be used as the attachment bone point. The attachment bone point can also be understood as the parent bone point in the cloak model. The cloak model is connected to the body part of the model through these attachment bone points, and the other bone points in the cloak model are connected to the corresponding parent bone points one level at a time, and finally constitute the cloak model.
[0091] S602, according to the multiple attachment skeleton points between each sub-model and the model, attach the flexible animation special effects of each sub-model to the corresponding position on the model to generate the target animation special effects of the model.
[0092] Optionally, for a certain sub-model, the flexible animation effects of the sub-model can be added to the corresponding position of the model according to the multiple attachment bone points between the sub-model and the model, so that the cloak part of the model has a fluttering effect.
[0093] On the basis of the rigid animation effects of the model, the flexible animation effects of the sub-model can be added to the model in the same way, so that on the basis of the rigid animation effects of the model, specific parts of the model also have flexible animation effects. For example: when the model is walking, the cloak will flutter in the wind.
[0094] Figure 7 A flowchart of another model animation processing method provided in an embodiment of the present application; optionally, the method of the present application may further include:
[0095] S701. Add root bones to each sub-model.
[0096] In some embodiments, in addition to generating model animations, this solution can also realize the free addition of model materials.
[0097] Optionally, root bones can be added to each sub-model in 3Dmax, and the specific adding process can be implemented based on the existing root bone adding function of 3Dmax.
[0098] The root bone plays a vital role in 3D animation and skeletal rigging. It is the starting point or foundation of the entire skeletal system, and all other bones are directly or indirectly connected to the root bone. The root bone is usually located at the bottom of the model (such as under the character's feet) or in the center, serving as the root node of the entire bone hierarchy.
[0099] S702: Determine at least one material slot corresponding to each sub-model according to the root skeleton of each sub-model.
[0100] The material slot is used to indicate the area in the sub-model where the material is to be added.
[0101] Through the root bones corresponding to each sub-model, the root bones can be identified to determine at least one material slot corresponding to each sub-model.
[0102] Material slots are areas or locations on the model surface used to carry and display different materials. Each slot can correspond to one or more materials, which can be a combination of properties such as color, texture, reflectivity, transparency, etc. By assigning different material slots to the model, you can achieve rich visual effects and detailed performance.
[0103] In 3D modeling software, material slots allow users to assign different materials to various parts of a model, thereby creating objects with complex appearance and details.
[0104] S703. According to the material slots corresponding to the sub-models and the to-be-added material information corresponding to the sub-models, add the corresponding materials to the material slots corresponding to the sub-models.
[0105] Optionally, based on the determined material slots and the material information to be added for each sub-model, corresponding materials can be added to the material slots of each sub-model to achieve free addition of materials. The addition of materials can enrich the visual effect of the model.
[0106] Figure 8 A flowchart of another model animation processing method provided by an embodiment of the present application; Optionally, in step S702, determining at least one material slot corresponding to each sub-model according to the root skeleton of each sub-model may include:
[0107] S801. Determine at least one target area on the sub-model according to the motion range of the root bone of the sub-model.
[0108] Among them, the target area is used to indicate the area directly connected to the root bone or controlled by the root bone.
[0109] Usually, you can analyze the position and range of motion of the root bone to determine the overall structure and motion of the sub-model, and then based on the range of motion of the root bone, determine which areas of the sub-model will be affected by the root bone's motion and use these areas as target areas. The target area is usually the part of the model that is directly connected to or controlled by the root bone.
[0110] S802. According to each target area, query and determine the material slot corresponding to each target area.
[0111] After determining the target area, you can find the material slots corresponding to the target area in 3Dmax. Usually, these material slots are listed in the model's material editor or property panel.
[0112] S803. Use the material slot corresponding to each target area as at least one material slot corresponding to the sub-model.
[0113] Then, the material slot corresponding to each target area can be used as a material slot of the sub-model, thereby obtaining one or more material slots corresponding to the sub-model.
[0114] Fig. 9A flowchart of another model animation processing method provided in an embodiment of the present application; Optionally, in step S703, according to each material slot corresponding to each sub-model and the material information to be added corresponding to each sub-model, adding the corresponding material to each material slot corresponding to each sub-model may include:
[0115] S901. Determine the material information to be added corresponding to each material slot in the sub-model according to the display effect corresponding to the sub-model.
[0116] In some embodiments, the material information that needs to be added to each material slot may be determined based on the display effect to be achieved by the sub-model.
[0117] S902. According to the information of the materials to be added corresponding to each material slot, add the corresponding materials to each material slot corresponding to the sub-model.
[0118] Based on the determined material information that needs to be added to each material slot, corresponding materials can be added to the material slots corresponding to the sub-model to achieve the desired display effect.
[0119] For example: if you want to make the outer layer of the head model glow and have a certain parallax effect, you can add a skin glowing material, such as skin_glitter, to the material slot of the head model so that the outer layer of the head model can glow.
[0120] Or if you want to achieve a deep starry sky effect on the head model, you can add a skin material with starry sky or galaxy effect in the material slot, for example: skin_galaxy material.
[0121] By adding a root bone, the material slot can be identified, so that different parts of the model can freely use different materials through the material slot, thereby improving the display effect of the model.
[0122] To summarize, the model animation processing method provided in this embodiment includes: splitting the model according to information of the part of the model where special effects are to be generated, to obtain at least one sub-model; adding wiring to each sub-model according to the target flexible animation special effects corresponding to each sub-model and segmenting each sub-model based on the added wiring to obtain each segmented sub-model; determining the first animation data of each bone point in each segmented sub-model in each frame according to the target flexible animation special effects corresponding to each sub-model; generating flexible animation special effects for each sub-model according to the first animation data of each bone point in each segmented sub-model in each frame; generating the target animation special effects of the model according to the flexible animation special effects of each sub-model. This method splits the model based on the information of the part where special effects are to be generated. For the sub-models obtained by the splitting, based on the special effects animation to be generated, wiring is added to the sub-models and the sub-models are separated, and editable bone points are added in the sub-models to make the sub-models editable and deformable. Based on the target flexible animation special effects corresponding to the sub-models, the flexible special effects animation of the sub-model can be generated, and the flexible special effects animation of the sub-model is added to the corresponding position in the model to generate the target animation special effects of the model. Through this method, the limitations of the production of flexible animation special effects in some games can be solved, the effects of model animation special effects can be improved, and the display effects and authenticity of the model can be enriched.
[0123] In addition, by adding a root bone to the sub-model, the material slot of the sub-model can be obtained through root bone identification, so that different materials can be freely added to different parts of the model based on the material slot, thereby improving the richness of the model's display effect.
