Is it possible to make a UV texture show with an alpha value, and if so, how would one go about this? I’m trying to make it so that most of the UV texture remains the same, but the basic material color below it is visible in some small portions and can be changed the same as always, without changing anything else in the texture. I tried just putting an alpha value in the TGA file, but this didn’t work too well as it all just turned up black. Any help?
The TGA file probably does have the alpha channel, but Blender ignores it by default. You have to select “Use Alpha” under the texture buttons tab.
It works! Thanks, I figured it was gonna be some bonehead-simple thing like that. 
I know, it catches me all the time, too.
