Shadow catcher with MDL?

Is it possible to to make a matte shader like Maya’s UseBG that allows you to create shadow mattes? Sorry if it is there and I don’t know how to activate it in the main shader. I see iRay has a ground plane option. Would be great to see that built in to the faster rendering options.
I do like the way Renderman uses the HoldOut tickbox on geo, that is a really simple way and it means the currenlty assigned shaders still provide lighting feedback. So maybe it is a geo solution and not a MDL one.

Hi delfemail,

Thanks for you interest! I’ll pass this along to the devs

This is currently in development and will be out in a couple of months. You can set any object as a shadow and reflections catcher.
