i just got maya 2008 and my diffuse map is not rendering..i tried it on my art director's computer and it rendered on his..the diffuse would only render in maya software never in mental ray..any ideas on fixing this problem will be greatly appreciated

I was having the same problem. It seems mental ray connects the outAlpha of your diffuse map to the diffuse channel. So if your diffuse maps don't have an alpha channel....they ain't be workin' ...rY

And if that is the problem, dont forget that there is a preference you can set called "use maya-style alpha detection on textures", or you can do it on each fileTexture's attributes by checkking "alpha is luminance", in the color balance tab. (In previous versions of maya this was actually the default).

Wow I really appreciate you all for this. In a middle of a project I switched from Maya v8 to Maya 2008 and when I loaded my scene I was horrified to find my Diffuse and eccentricity maps where not responding and defaulting to all 100% value.
So thank you all for helping me with this, I just clicked on alpha is luminance to fix...somthing new I have to learn about the newer Maya after using this software on and off for about 3 years.
Thanks again :)
