Decal on parts of a robot?

[rohit-kumar-j]

I understand that Mujoco is not intensive on graphics of parts, etc... However, is there an example to put a decal on a part of a robot in Mujoco? I had seen this on the older forum. But was unable to reproduce it, especially for complex .stl files.

As of version 2.1.2, MuJoCo supports OBJ meshes, which have simpler texture mapping.
If your 3D software can export OBJ and a texture, you can use it as shown in https://github.com/deepmind/mujoco/tree/main/model/mug
