Unity의 물리와 조명 시스템에서는 게임의 1미터를 임포트된 모델 파일의 1 단위로 간주합니다.
다양한 3D 패키지의 기본값은 다음과 같습니다.
스케일링 인자가 다른 3D 모델링 애플리케이션의 모델 파일을 Unity로 임포트하는 경우, Convert Units 옵션을 활성화하여 파일 단위를 Unity 스케일로 변환할 수 있습니다.
Before you import your files into Unity, there are a number of steps you should follow to ensure that your files are optimized in the best way.
Think about what you want to export: some scene objects are essential but others might be unnecessary, so you can optimize the data in Unity by keeping only the essential objects. This helps remove unwanted data from your scene, and also means you can use a preset or custom scene exporter to automate or simplify the export process.
The following table outlines special considerations you should make for each asset type to work most optimally in Unity:
| Object | Preparations |
|---|---|
| Meshes | 모든 NURBS, NURMS, 스플라인, 패치 및 subdiv 표면을 폴리곤으로 전환(삼각형화 또는 사각형화)해야 합니다. |
| Bake deformers | Make sure that you bake deformers onto the models in your application before exporting to the .fbx file format. For example, if you want to export a complex rig from Maya, you can bake the deformation onto skin weights before you export the Model to .fbx. |
| Textures | Make sure the textures in your application are either sourced from your Unity Project, or copy them into a folder called Textures inside your Unity Project. Note: Don’t use the Embed Media option to embed textures into the .fbx file. Because Unity has to extract the textures before it uses them, embedding them enlarges your project and slows the import process. |
| Smoothing | If you want to import blend shape normals, you must have smoothing groups in the .fbx file. |
Before you export the .fbx file, make sure that you use the latest .fbx exporter version that your 3D modeling application supports. When you export to .fbx, make a note of each setting in the export dialog of your 3D modeling application so that you can match up the .fbx import settings in Unity. Most .fbx exporters allow you to enable or disable exporting of certain animations, cameras, and lighting effects, so if anything is missing when you import it into Unity, check to see if it was exported.
Before importing your .fbx file into Unity, verify the size of your exported file. Perform a sanity check on the file size (for example, to see if it is larger than 10KB). Re-import your .fbx file back into the 3D modeling software you used to generate it (for example, into a new scene). Check to make sure it is what you expected.
