Problems solved by technology

[0013] 1. Exporting models from 3D software and repeatedly importing models from UE4 has a long production cycle and high cost;
[0014] 2. The coordinates of the imported FBX model in Unreal Engine 4 cannot accurately match the coordinates, direction, and scaling of the 3D software;
[0015] 3. It is inefficient to manually set the world environment parameters one by one;
[0016] 4. Manually adding reflective balls repeatedly is inefficient;
[0017] 5. The volume efficiency of manually adding lights repeatedly is low;
[0018] 6. The volume efficiency is low in the later stage of manual repeated addition

Embodiment 1

[0058] Such as figure 2 As shown, one embodiment of the present invention comprises the following steps:

[0059] In the 3D software, the 3D model and scene data are generated into exportable 3D model data files and 3D data information files;

[0060] Start the Unreal Engine4 engine;

[0061] In Unreal Engine4, read the 3D model data file and 3D data information file, and restore the center point coordinates, direction and scaling of each model.

[0062] Among them, the scene is composed of multiple models.

Embodiment 2

[0064] On the basis of Embodiment 1, in another embodiment of the present invention, in the 3D software, generating an exportable 3D model data file and a 3D data information file from the 3D model and scene data includes the following steps:

[0065] Clean up redundant data in the 3D software scene;

[0066]Generate 3D model data files in FBX format and 3D data information files in XML format according to the scene and model data.

[0067] Among them, the 3D model data file in FBX format and the 3D data information file in XML format are two files. FBX is a cross-platform free 3D creation and exchange format software produced by Autodesk, through which users can access 3D files from most 3D suppliers. The FBX format supports all major 3D data elements. These three-dimensional data elements, such as vertex coordinates and face IDs in the model, etc. The 3D data information file is an XML format file, which is used to record the relationship between the entire model, materia...

Embodiment 3

[0069] On the basis of embodiment 2, said clearing up redundant data in the three-dimensional software scene includes:

[0070] Unlock and unfreeze all models;

[0071] Clean up junk data;

[0072] Configure UV and UV channels;

[0073] Retrieve whether there is missing texture light information;

[0074] Separate all multidimensional sub-shaders;

[0075] Merge models for related materials.

[0076] The garbage data includes: 2D lines, particles, empty objects, all lights except TargetSpot / TargetDirect / Omni / FreeSpot / FreeDirect / Skylight / Vraylight / VrayIES / VraySun / Vray Ambient Light, all cameras except Freecamera, mr Lighting effects, referenced files, invalid lines.

Abstract

The invention discloses a method for automatically inputting three-dimensional (3D) model and scene data to the UE4. The method comprises steps that in the three-dimensional software, 3D model and scene data are made to generate an outputtable 3D model data file and a 3D data information file; the Unreal Engine 4 engine is started; in the Unreal Engine 4, the 3D model data file and the 3D data information file are read, and center point coordinates, the direction and the scaling ratio of each model are restored. The method is advantaged in that VR content making efficiency is substantially improved, the making period is shortened, cost is directly reduced, repetitive operation of processing object coordinates in the 3D software is simplified, one-click batch automatic processing in the 3Dsoftware is realized, and the model, coordinate, orientation and size information can be rapidly inputted into the Unreal Engine4.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a method for automatically importing three-dimensional models and scene data into UE4 (Unreal Engine4). Background technique [0002] At present, there are usually three ways to make VR (virtual reality) scenes (1. Use UnrealEngine4 game engine; 2. Use Unity3D game engine; 3. Use self-developed engine), and Unreal Engine4 is currently recognized as one of the best engines in the world , can realize high-quality real-time interaction, and its picture effect can reach more than 90% close to the realistic rendering. [0003] The existing solution is a fully manual operation, exporting the scene / model made in the 3D software, and then manually importing it into Unreal Engine4. Such as figure 1 As shown, the specific process is: [0004] 1. Unwrap the UV of each model in the 3D software and set the UV channel; [0005] 2. Since Unreal Engine 4 cannot restore the coordinate...
