Use UV Maps to differentiate 'factions' in an RTS type game?

[Kurt-Dekker]

Usually this is handled by swapping entire Materials out, one Material for each team.

Alternately you can have multi-material objects such that some is shared, some is differentiated and associated with team color.

If you wanna get the UVs, give it a shot (they are in a Vector2[] in the Mesh, available from the MeshFilter), but I’m not sure what interactions you might have with ProBuilder today, as I haven’t used that package in a long time and I think it used to rebuild the mesh contents at load time, which means you would need to ensure you do any UVs swapouts after anything ProBuilder might do.

If you want to colorize by swapping out materials, keep this in mind:

Materials materials array of materials renderer:

Generally accessing .material / .materials is going to give you a fresh copy. (See docs for why and when)

Changing material colors was working, now it is not?

This is the problem. You want to either: a) create a fresh array of material references, fill them out with Materials, then assign it back to the renderer OR b) copy out the array, make the changes you want, and put it back. I prefer option b generally, but you may have a reason for the other. It can look something like this: var tmp = new List<Material>( rend.materials); tmp[0].color = ... tmp[1].color = ... tmp[2].color = ... rend.materials = tmp.ToArray(); Or you can use good old Sy…

Adding and removing a material at runtime

If you have an object with multiple Materials, that ALSO implies that the mesh has multiple submeshes. Each Material in the .materials array corresponds to a submesh, so just adding a material to an object isn’t likely to do much. If you think you still want to, you need to: create a new blank array of Materials of the right size (+1 or -1 in size) copy the existing Materials out to the correct spot in this temp array add (or omit) the newly added (or removed) material. assign the array of M…
