[i can't make vehicle doors animations]

Although I do the same as the blender file in the game files, the animations do not work in the game and sometimes it crashes. I want to add animation to the car doors, can you give me a tip on how to do this?

what shader are you using for the chassis model?

 

if you are using the multiuv shader, you need to assign your uv map to the 2nd uv channel of your model too. just copy it over to the 2nd one and the things will show up

 

oh i forgot make 2. uvmap and thanks for the reply.

 

but I still don't know how to color it
