Shadow only render pass ?

[negicless]

Hey, I am currently working on a project that needs a separate shadow pass to do composition in aftereffect, since there is no built-in soft shadow support right now, is there a way to render only shadows?

There are no built-in Render Passes types in Malt, but you can do it with custom outputs (AOVs). See #91 (reply in thread).

For getting only shadows you can do something like this:

shadow-aov.zip

If you're going to move the result to After Effects anyway you can simply use the shadow pass from Cycles too.
