Has anyone else had problems with volumetric materials? Sometimes they render without any problem, next time they look like a blue-green-red-colourinterference. Entering a volumetric area with a camera during an animation results in the same effect. (I tried to create a "follow-the-missile-to-target-animation" yesterday and wanted to add some stylish volumetric clouds - imagine the clouds looking fine from the outside and red-blue-green from the inside...) And another bug that bugs me since Vue 2: While saving an atmosphere - especially volumetric atmospheres, the programm freezes far to often - almost 8 times out of 10. That's a bit to much if you ask me. (OK, my computer has only 224 MBs of RAM, but at least it should try to render and not stop at 1%.) Joerg
