I have something I want to try, but I cant figure out how to make it work. I want to make fog/smoke billowing into the camera. I want it to have high cotrast, lots of movement, and be able to alpha everything thats not smoke/fog. I am working on an expermental cg animation process in after effects and I would like to use carrara to generate the displacment maps. The problem was last week end I made a blimp and tried to recreate the hindenburg....the stupid thing rendered all weekend and when I got back on monday the fire never animated!!! I even hit shuffle!!! Do I have to hit suffle for every key frame?? Has anyone ever animated smoke/fire?
