I applied a material on one of my models and then i notice that my material applied on all 2 out of my 4 models so, after trying to make my material apply only to my 1 our of 4 models i ended up the material to be applied on all 4/4 of my models...why? Are they connected somehow?
Edit: ok i found it!
My mistake was to make unique the material only! i should make unique the model MeshInstance>Mesh>Make unique
