I've been going through some video tutorials for After Effects and came across the section for 3D channel filters. I know if you render out a Carrara scene in certain formats, you can retain 3D info such as distance and 3D position. After Effects is looking for this info in RPF or RLA format which other 3D programs support. Is there a way to convert the Carrara output to a similar format (even with a 3rd party utility)? Thanks.
