MentalRay Gets Bitchy On Transparency Map

http://www.3dbuzz.com/vbforum/showthread.php?t=158984 If this transparancy map is a file texture and you are using maya 2008 then you will need to check the "alpha is luminance" flag in the file texture attributes. This is an assumed default for the software renderer, but not for mentalray. this is a new setting turned off by default in maya 2008 hope this helps

Ideally it will be a piece that combines motion graphic and 3d visual effect. Sorry if some transitions in between is not very clear right now. It took me a long time trying to make it informative and making sense in a way. I also took the suggestion of Ethan from midterm presentation and tried to make the OS sounds more personal. ...
