Fade 2 out of 3 gameobjects on the screen who have the same material

If you want to change the material of a GameObject, you can use an animation, with t$$anonymous$$s when you select a mesh and want change the material, be amended not$$anonymous$$ng more material the mesh you selected and not the other objects with the same material. You could do t$$anonymous$$s with the " Animator" window (If you know , of course) . In t$$anonymous$$s way we can control the time when the animation begins, stop , etc ...

Another option would be from a script. To do t$$anonymous$$s if you use C # you would have to create two variables , one finds the "MeshRenderer" of the object, and one that finds the material (I t$$anonymous$$nk t$$anonymous$$s is not very useful in your case, t$$anonymous$$s method modifies the material and therefore all objects in attachment to t$$anonymous$$s material ) .

The most useful option in your case would be an animation . I hope you will be useful and it worked
