Hello
I have a simple scene a sphere and a grid plane, just want to test how I can render out a ground plane as a shadow catcher (matt object, with shadows on it).
I can't find the way to do it in solaris and karma Xpu.
please let me know how I can do it.
thank you in advance
Karma XPU, Matt Shadow catcher

It should work as the doc says but unfortunally the shadow layer is empty with karma XPU!
It works with karma by the way. but I need XPU version for faster render.
PS: That's the principed shader inside Backgourd plate subnet that makes it uncompatible with XPU version.

XPU doesn't support the necessary AOVs yet, so it's not possible.

Hi Guys, I'm now moving to XPU from many years of using Arnold, XPU is such a great renderer, the only issue I have with my renders is the Shadow Matte, I have been using a plane with a texture on it's Opacity channel to blend the plane into the Dome Light's map so I can catch the shadows, this works o.k. for still shots, but takes quite a bit to set it up.
Is there any eta on when a shadow catcher will be added to XPU?
Again, great work on this beautiful renderer.

How about this?
It's a basic scene I've used for testing.
Here are the docs for the background plate too

Thank you for the sample.
Is it also possible to have no plate image just transparency directly saved out like in the pitures below.
In this scene I had a shadowCatcher Material on the floor.

When I set the render engine to XPU the render takes quite a bit longer than CPU, and I don't think you can get the same effect as a shadow matte (Shadow Catcher) with an environment light hdri, unless this ability is hidden somewhere.
I think it would be essential for later compositing where you load the background footage.
It would be cool to have a ShadowCatcher Material.
