Unity3D can automatically import ma, mb, and fbx files. After editing them in Maya, drag them directly to the Unity Resource Panel or store them in the Unity project folder, will be automatically identified and imported.
Note the following when importing data:
1. Special Functions of Maya are not supported, such as dynamics, particles, fabrics, etc.
2. Check the bake animation option if any problem occurs during animation import.
3. If you have skin, Use smooth skin. Unity does not support Rigid Body skin or any vertex animation.
4. animations made by the HumanIK system are also supported and can be recognized directly. If you do not need a new Unity animation system, you can directly select the legacy mode on the rigid panel.
5. If the animation is divided into multiple Clip segments, name the clip segments respectively during the import.
6. you need to manually add the texture, and Unity cannot find the texture when importing the model. Maybe I didn't try it out.) Select the corresponding Material, and then manually select the UV texture in the UV texture.
In short, it is relatively simple.
