View Full Version : MR transparency with atmospheric

10-19-2010, 04:24 PM
Hey everyone, I need a hand. I have a pflow setup using sprites with a texture mapped into the transparency channel. Everything seemed to be working out ok until I turned on my atmospheric fog. I am using the normal 3dsmax Volume fog and I seem to get weird issues with my transparency (see images). I am in max2010 and rendering with MR. Anybody have this issue before or know anyway to fix it?
Thanks for the help.

Haven't seen it before, but messing around with it for a minute, I was able to get it to work, at least for me anyway.

Enable Exponential in the Volume Fog


Turn on AutoVolume in Mental Ray

Little example: Has volume light and volume fog in it (only one is activated currently)

I really appreciate the help, turning on Exponential and Auto Volume seemed to do the trick. Thanks again!
