Description

Technical Field

[0001] The present invention relates to the technical field of Unreal Engine resource management, and in particular to an Unreal Engine 5 resource automatic packaging system. Background Art

[0002] In the current game and application development process, resource management and application packaging are two key links. Especially when using advanced game engines such as Unreal Engine 5, the challenges faced by developers are more complex. Although Unreal Engine 5 provides highly optimized and powerful rendering capabilities, there are still some technical issues in efficiency and compatibility in resource import and project packaging.

[0003] First, the resource import process is still done manually in many projects, which is not only time-consuming but also prone to errors. Developers need to convert resource files of various formats (such as 3D models, textures, audio files, etc.) into UnrealEngine5 compatible formats and ensure that these resources are correctly loaded and displayed in the engine. If this process lacks automated tools, it will greatly increase the project development cycle and reduce the work efficiency of the development team.

[0004] Secondly, after the resource import is completed, the project packaging process also faces efficiency issues. Although UnrealEngine5 provides certain packaging tools, developers often need to perform a lot of configuration adjustments and optimization work for multi-platform releases of complex projects. In addition, as the scale of the project increases, the time and computing resources required for the packaging process also increase significantly, which is a big challenge for development teams with limited resources and time.

[0005] In addition to efficiency issues, compatibility issues during resource import and packaging cannot be ignored. Since games and applications need to support multiple hardware platforms and operating systems, developers need to ensure that all resources can be displayed and run correctly on different platforms. This not only involves the conversion of resource file formats, but also includes consideration and optimization of performance limitations of different platforms. Summary of the invention

[0006] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide an UnrealEngine5 resource automatic packaging system.

[0007] The purpose of the present invention can be achieved by the following technical solutions:

[0008] An UnrealEngine5 resource automatic packaging system, the system comprising:

[0009] Resource management subsystem, which identifies and processes imported resource files of different types and formats;

[0010] The packaging engine parses automated packaging and automatically executes the entire process from project compilation to final packaging, including asset baking, file location and mounting, index parsing, and resource request and loading.

[0011] As a preferred technical solution, the resource management subsystem identifies the types and formats of resource files including but not limited to 3D models, textures, audio and video files; the resource management subsystem analyzes the properties of resource files including file format, size and complexity, and converts and optimizes these resources according to the best practices of UnrealEngine5.

[0012] As a preferred technical solution, the packaging engine parses the automated packaging command line as follows:

[0013] Constructs an UnrealPak command line string based on the information provided by the user;

[0014] Parse the parameters in the UnrealPak command line string through the UnrealEditor-Cmd.exe tool and determine the user's intention; wherein the parameters include the target platform, configuration, project path, and script file path; the user's intention includes: packaging, building, baking lighting, and running automated tests;

[0015] Based on a command line string, launches an UnrealPak process and monitors its execution.

[0016] As a preferred technical solution, the asset baking is specifically as follows: sampling the scene, subdividing the surfaces of all geometric bodies in the scene into multiple sample points, and calculating the lighting information of each sample point.

[0017] As a preferred technical solution, the light map is compressed during the baking process to reduce the resolution of the light map.

[0018] As a preferred technical solution, during the baking process, the density of sampling points is optimized according to the complexity of the object and the distance from the viewing angle.

[0019] As a preferred technical solution, the packaging engine performs file location and mounting as follows:

[0020] Based on the input project path, locate all available .pak files;

[0021] Mount the located .pak file to the virtual file system. The mounting process maps the contents of the .pak file to the engine's file system so that they have a normal file and directory structure.

[0022] The engine reads resources packaged in .pak files through standard file access interfaces.

[0023] As a preferred technical solution, the .pak file contains an index, which lists the paths and location information of all resources therein; when loading, UnrealEngine will first parse the index contained in the .pak file to obtain the location and size of each resource in the .pak file.

[0024] As a preferred technical solution, the .pak file uses encryption and verification mechanisms to ensure data integrity and security; when loading, the engine will verify the signature and integrity of the file to ensure that the resources have not been tampered with.

[0025] As a preferred technical solution, the system also includes a monitoring and logging mechanism, which monitors the execution status of the entire automated packaging process in real time, records the output of UnrealPak and displays it in real time in the GUI; records key events and possible error information, and gives result prompts after packaging succeeds or fails.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The present invention provides a technical solution that can automatically process UnrealEngine5 resource import and one-click packaging, which becomes particularly important. Such a solution can not only significantly improve development efficiency and reduce error rates, but also ensure the compatibility and stability of the project. Especially in modern game and application development, the ability to quickly iterate and adapt to the needs of multi-platform release has become an industry standard. Therefore, solving these technical problems will not only help improve the development efficiency of a single project, but also help promote technological progress and development of the entire industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 It is a schematic diagram of an UnrealEngine5 resource automatic packaging system of the present invention. DETAILED DESCRIPTION

[0029] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0030] Example 1

[0031] This invention provides an automated solution for the resource import and one-click packaging process of Unreal Engine 5. This technical solution aims to solve efficiency and compatibility issues through innovative automated processes and tools, thereby optimizing the development process, improving development efficiency, and ensuring the quality and compatibility of the final product. Figure 1 As shown, the system specifically includes:

[0032] First, for the resource import process, the invention proposes an intelligent resource management subsystem. The system can identify and process resource files of different types and formats, including but not limited to 3D models, textures, audio and video files. It can analyze the properties of resource files, such as file format, size and complexity, and then automatically convert and optimize these resources according to the best practices of UnrealEngine5.

[0033] Verify the validity of the UnrealPak tool path and resource directory path entered by the user. If either path is invalid, the software will prompt the user to correct it. Import the model and put the materials, textures, etc. into the corresponding folders. Check whether the static mesh material is given. If not, put the texture on the material ball and assign the material to the model. Save the added content, but be careful not to save the current scene file. If you need to use the scene when testing, create a new folder to store it to prevent the test scene from being baked into the cook.

[0034] The present invention is aimed at the one-click packaging process, and the present invention has developed an efficient packaging engine. The packaging engine is tightly integrated with UE5, and can automatically execute the whole process from project compilation to final packaging, including steps such as resource binding, dependency checking and performance optimization. It supports multi-platform packaging, and can adjust the packaging strategy according to the characteristics and requirements of different platforms to ensure that the final generated application has the best performance on the target platform. In addition, the packaging engine is also highly configurable, and developers can customize each link of the packaging process according to the specific needs of the project. The specific implementation of each link of the packaging process is as follows:

[0035] 2.1. Automatic packaging command line parsing

[0036] Construct the correct UnrealPak command line string based on the information provided by the user. This process requires precise processing of various parameters and options to ensure that the command finally executed correctly reflects the user's intention. The constructed command line string is executed through the C++ system call function to start the UnrealPak process and monitor its execution process. The software should be able to capture any execution errors and feedback to the user through the GUI. Specifically: find the UnrealEditor-Cmd.exe file location through the UE path saved by the user, automatically execute the command line, parse these parameters through the UnrealEditor-Cmd.exe tool, and determine the user's intention (such as packaging, building, baking lighting, running automated tests, etc.). These parameters usually include target platform, configuration (such as Debug or Release), project path, script file path, etc.

[0037] 2.2. Baking assets

[0038] During the baking process, the scene is first sampled. All geometry in the scene is processed, including static meshes, terrain, etc. The surfaces of these objects are subdivided into multiple sample points (Texels) to calculate the lighting information for each point.

[0039] In order to reduce the storage space occupied by lightmaps and the use of memory, lightmaps are compressed during baking and the resolution of lightmaps is reduced. During the baking process, the density of sampling points is optimized according to the complexity of the object and the distance from the viewing angle. This process is particularly important for static scenes or static objects in the scene, which can greatly improve rendering performance and maintain high visual quality.

[0040] 2.3. File location and mounting

[0041] The software locates all available .pak files through the project path entered by the software. After finding the .pak file, the engine will mount it to the virtual file system (VFS). The mounting process maps the contents of the .pak file to the engine's file system, giving them a normal file and directory structure. This step allows the engine to read the resources packaged in the .pak file through a standard file access interface.

[0042] 2.4 Index parsing

[0043] The .pak file contains an index that lists the path and location information of all the resources in it. When loading, UnrealEngine will first parse this index so that it knows the location and size of each resource in the .pak file. Parsing the index can speed up access to resources because the engine does not need to traverse the entire file every time to find a specific resource.

[0044] 2.5. Resource request and loading

[0045] The data in the .pak file is usually compressed to reduce the file size. After extracting the resource data, Unreal Engine needs to decompress the data and restore it to the original resource file format.

[0046] If the resource is encoded (such as audio, video), it needs to be further decoded after decompression before it can be used. It is usually stored in a specific encoding format (such as MP3, AAC, H.264, VP9, ​​etc.).

[0047] The decoding process is usually a loop: read data blocks, decode data blocks, process the decoded data, and output the decoded data

[0048] 2.6 Security and Verification

[0049] .pak files can use encryption and verification mechanisms to ensure data integrity and security. When loading, the engine will verify the signature and integrity of the file to ensure that the resources have not been tampered with.

[0050] The invention also includes a monitoring and logging mechanism to ensure transparency and traceability of the resource import and packaging process. This mechanism can monitor the execution status of the entire automated process in real time, record key events and possible error information, and help the development team quickly locate and solve problems. The software records the output of UnrealPak and displays it in real time in the GUI, allowing users to track the packaging process. After the packaging succeeds or fails, the software should give a clear result prompt.

[0051] In general, the present invention realizes the automation, optimization and standardization of UE5 resource import and one-click packaging process by introducing an automated resource management system and an efficient packaging engine. This can not only significantly improve development efficiency and project quality, but also improve the market competitiveness of products, bringing significant technological progress and commercial value to the game and application development industry. Through this innovative technical solution, the present invention is expected to become a new standard for resource management and packaging in UE5 development, promoting the development of the entire industry.

[0052] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
