Is it possible to define the master visibility of a GameObject/mesh renderer? I am vaguely aware that fading a mesh out can be done by getting its material and changing the alpha value of it. However, perhaps my Blitz Basic 3D legacy has spoilt me with this feature, but I like the idea of an object opacity variable. Is there anything like this in Unity? For example, if I have a hypothetic complex object with dozens of materials it seems clumsy getting them all and fiddling with the alpha.
Is there a much better way to fade out a mesh that I am overlooking?
