I am trying to retexture a Community-Made model from the game Team Fortress 2 called the Bi-Decoder (Google it- or Bing if you're that kind of person -if you don't know what it looks like. I can't link any more pictures.) The screen on the model is made of two parts. A transparent (but slightly translucent) material that gives the screen it's convex shape, and a layer underneath that has the actual contents of the screen mapped on to it. The screen's contents are supposed to look like this:
However, when I render the model, the Transparent layer is black and opaque!
(Everything is set up to run in the Blender renderer, not Cycles.)
Is there something I'm doing wrong? Help would be greatly appreciated. Thanks!
