Oh, that's very cool. Tell me more about this depth map matte technique - sounds intriguing.
Masqutti's idea. Basically, I copied my model and made everything white. Set up a distance fog that dropped to black, and adjusted the fog until I had the correct transition. Embed the depth fog render and use as a luma matte.I have two different "Depth passes." one for the columns, masking the atomic particles and fire, the other for the floor to cut off my particle fog.Oh, Revision 3.http://www.youtube.com/watch?v=uW2PDqBPtXIEDIT: Revsion 3 has been deleted from youtube.
