Clip Geo not working with Shadow Matte?

[ingmar.wittmann]

Shadow-matte is shown in the render-view but not stored in the alpha channel.

Works fine.
Remember to detick the Alpha Mask in the Matteshader.

Thx for your reply, i need the shadow on the floor to be masked.

[ingmar.wittmann]

only added the clip geo shader and the Matte of the Shadow is gone

Then keep the tick on.

The shadows are caught by the matte surface as seen here.

upload the scene somwhere, so I can take a look at your setup.

here is my file, the hdr(enviroment) image is not included

I downloaded your scene and change a few things.

Notice the correct alpha on the matte, the shadows are included.
Notice the correct blend on the RGBA.

Attached the scene, replace the hdri.

Use the latest Arnold build just released today and use ARV render view instead of using VFB+ The new drop includes grading tools.
