Hi!

I'm Tanner from GameTextures and I can definitely help you here!

So, Maya's Real Time renderer is going to be a bit different than a game engine, but it still works the same for the most part.

To begin, you *should* be using the Phong shader in Maya for our materials.

Your Diffuse map (_D.tga) goes into the Diffuse Field

Your Emissive map (_E.tga) goes into the Incandescence Field.

Your Specular map (_S.tga) goes into the Specular Color field

Your Gloss map (_G.tga) goes into the Cosine Power field)

Your Transparency map (_T.tga) goes into the Transparency Field (If it appears to be backward, you can invert it directly in maya by going to this option and selecting it:

As of now, there is no way to use the Height map in Maya for real time, unfortunately.

If you need any more help you can email me at tanner [aaaat] GameTextures.com and I can help you further!

Hope this helps!

Tanner
