Custom shadow catcher.

Does anyone have a reliable custom shadow catcher node setup? Mine is good for smaller scenes, but every time I render a bigger one, for some reason the computer goes into deadlock, it has happened multiple times so far. It’s really annoying.

Here’s the node setup I’ve been using this whole time:


There is a proper shadow catcher shader in the buildbot builds now, probably easiest just to use that: https://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.79/Cycles

My setup there works very well.

Yeah, but:

It is to be noted that shadow catcher objects will interact with other CG objects via indirect light interaction. For example, shadow catcher will be reflected in the glossy surfaces.

I predict this will cause a lot of grief.

Almost forgot to say that the solution is oaschwab’s shadow catcher. It works pretty well.

The ray visibility switches still work for shadow catchers. Just disable any you don’t want, as you would any other object.

@J_the_Ninja Ah, of course.
