I wondered if anyone’s been using the new version of composure yet? I’m quite impressed with it and can get it to do most of the compositing I need except for one minor detail with shadow catching.
I’m using a white material as my ‘floor’ and ‘wall’ which my objects can cast shadows onto, then I can multiply that output onto my background plate to add shadows to it. It works well except I can’t make the material a perfect white - it’s fine where the light sources are strongest, but where the light falls off it creates a false shadow.
In short, what i really need is essentially an unlit white material that can receive shadows but not light. Anyone else found a solution to this, or is there a better way to catch shadows. (In my setup I have mask out my shadow casting geometry too - actually, maybe I don’t need to do this, thinking about it.).
I guess i’m really waiting for proper documentation or a sample project for the new composure - the shadow catching worked quite well in the last version’s example project but I had no idea how it was done.
