Materials override

[Leonidas]

Hi @grzesiekmq,

If both the body and the wheels use the same material, then it’s expected to get the same color when you update that said material.

If you would like to change the color only on a specific mesh instance / instances, then you have to either clone the material (use unique materials per model) or use setParameter instead of updating the material.

Check the following thread on how to do that:

Change material diffuse tint color

Either clone the material and assign the cloned material to the mesh instance after which you can change whatever property of the cloned material you want or instead use meshInstances[0].setParameter('color_diffuse', [r, g, b]).
