Mental Ray help please.
Hi, everyone. I'm starting to learn Mental Ray, and I ran into this problem while trying out a "simple" GI scene.
http://img.photobucket.com/albums/09...ay_Problem.jpg My curtains seem to be glowing for some reason. Any help would be much appreciated. :headbang: |
these are photons bouncing back , absorbing colour information probaly the reason why it has a blue-ish glow.
u have to let the photons through the curtain , the curtains (actual geometry) is bouncing the photons causing indirect illumination. thats all i know. |
btw what kind of lightsource do u use?
Mental ray area lights? Do these lightsource emit photons? |
Thanks, herr_klaus. For this scene I'm using a spotlight actually, and yes it is emitting Global Illumination Photons.
I suppose I could pull the curtains a bit further apart to let the photons in. Or make the curtains a bit transparent. And while I'm asking, anyone have any workflow tips on MAYA Mental Ray GI? Thaks |
i can't remember how i bypassed this problem.
I had this problem before but very long time ago. tips ? always use a sealed compartment don't let photons escape. |
