A;pha/Transparency Maps in your diffuse

RedRaven

This probably seems like a pretty basic question, but so far in my studies since I began last year, I've yet to have the need for one.

Basically, I'm at a loss for finding a good tutorial or article that explains how to create an alpha/transparency map. At the moment I'm needing one for part of my model to apply transparency to glass on my mesh. I've got most of my main diffuse sorted out, but I wanted to test out transparency of the glass before I continue,as I still need to texture the internals of my model that'll be seen through the glass.

Any help is appreciated!

Well it sounds like you're almost there... yes, usually the transparency map is stored in the alpha channel of the diffuse bitmap. Here's a wiki article about it (I just added some more info for you):

What software are you using? How to create the transparency depends a great deal on what software you're using the render your model.
