There are some useful camera options in e.g. Apple Motion:
Any idea how to create fade in effect in Blender for objects close to the camera, moving away from camera? I know I can create keyframes for each object transparency but I have hundreds moving objects on the scene.
The obvious idea is to render several viewlayers separately (1.environment, 2.characterA, 3.characterB and so on) and do it in comp This requires having at least a minimal comp pipeline. Is setting it up a worthwhile use of time? is it needed for only 1 shot?
Doing it at the render stage on the other hand, would mean building the fading mechanism into each material separately. It can be done but it’s less flexible. Ultimately it depends on what you’re doing exactly.
