basicly I have a 3d logo made in AE to go on a 3D screen however I need to create a Z depth along side it of the image to work. I have used a back ground with a ramp effect and matted out the alpha which works, but when i want to move the camera it doesnt, well other than going frame by frame and editing it. any ideas?
Buena Depth Cue, now Digieffects. Possibly one could also use some expressions to auto-adjust the gradient as the camera moves around, but that would require to know the exact structure and layout of the scene.
