We are currently involved in the creation of CG's for a music video. The director is proposing to composite live action and CG's together. We have employed this technique many times for BBC Telivision with great sucess. This time however the camers shot is a moving one. Clearly a challenge but with the new perspective matching tool in R4 we felt this would be achievable. Unfortunately the perspective matching tool is only functional in the 3D editor making it imposible to perspective match a camera to a path in the keyframer. We feel this would be an extremely useful tool and, possibly not to difficult to generate. The bitmapped backgrounds could be manually reassigned if only perspective matching could load in the keyframer and function with relation to the time line. Is it possible to dissable fast preview mode, and enable perspective match in the keyframer? Could this be achieved via an additional code in the keyscripting language or from another source. Your help and advice would be much appreciated. Chris
