Quick render demonstrating a problem with Blender 2.5 Alpha 1 volume material. The scene is lit by one sun lamp and one hemi lamp. For some reason I can't get rid of the flicker. If anyone else has played with volumetrics and can help, please let me know. I've tried everything I know... :(
Addendum: I just discovered pasteall.org!
The .blend file for this is now uploaded there at:
http://www.pasteall.org/blend/2464
and should stay there for about 5 weeks, I'm led to believe.
Feel free to grab it and play with it. (those now laughing should be thoroughly ashamed of themselves!)
