Hello everyone, I am trying to make a vehicle based game but I have a problem with the materials. If I change the root node of my vehicle to spatial type every material works fine, but if I change the type of the root node to vehicle body the wheel materials are not showing right. Why this happens? (I can share blend and godot files). Thanks.

When root node is spatial :

Materials are fine:

But I need to use vehicle body node for my vehicle setup, so I change the type of the root node to vehicle body:
