Shared materials over muliple players

hello @Gvrv You can add script to set color individual, If you have instantiate gameobject

With help of

   gameObject.renderer.material.color = Color(0.777, 08, 0.604);

or

 gameObject.renderer.material.color = Color.white;

This will not change color of prefab.

By no means do I know much about sharing components, but have you looked at http://docs.unity3d.com/ScriptReference/Material.CopyPropertiesFromMaterial.html ? You could probably use that and just have a script that'll copy the material off a "master" Player, and attach it to each actual player, then copy over everything. Then you can use stuff like SetColor and such to change them if you need to.
