I have two questions regarding texturing models. I have found the answer to one of these questions a couple years ago on the old Facepunch forums but I can't find it now.
First, I am trying to have a sort of overlay over a model. A main, clean texture is applied, and then I am trying to add scratches to show wear over time without completely overriding the original texture. Is there any way to achieve this? I think this is more of a Lua question than a modelling one.
Second, I am trying to make only a portion of a model color-able. This is for Garry's Mod . I want to have most of the prop maintain its color and have other portions be white so I can have one prop and just change color information on it depending on what its function is or what it contains.
Thanks for the help! Sorry if this is the wrong forum, most of the discussions seem to have disappeared since I was last on here.
