Options for putting decals on low poly objects (not using vertices)?

xhi

I'm working on some objects that are low poly, like weapons and clothing around 250tris.  Is there a way to add decals without using vertices?  Do vertices even matter?  I'm imagining it being like vertex painting.

If I made a game in Unity where the user can put stamps on their clothes or weapons, how could that be done?  Any help or links to other related topics are appreciate

You would need a multi-layered shader and a way to manipulate the position, rotation and scale of the decal's UVs.
