I have been having some problems using Mental ray for maya4.5.
Please see the three attached images, the top one was rendered using Mental ray, the middle was when I went to batch render the same file. It seems to have lost all my settings and I have looked everywhere and set everything I could find to use Mental Ray render. Is the version of mental ray fron Aliaswavefront a full working version? Am I missing something obvious?
The last image is an earlier Maya software render, notice the shadows, you can see the shape of the fish and subtle shadows from through the glass. I have used Mental ray because I wanted to get caustics to render as in the top image but the shadows aren't rendering good enough.
I have limited knowledge of Maya & mental ray and am a relitave newbie to this whole game, from what I understand of raytracing I have to increase the rays so they penetrate the glass, I have tweeked with loads of settings and using mental ray I never get the same effect as with maya software...
Any help will be much appreciated!
