Hey there!
I have an explosion and I want to render the ground as a seperate element with only the shadows from the debris, volume. When using forced phantom for the debris it works nicely and I get only the shadows but the volume is always visible in the final render. I tried a mix og visibilty / matte settings in the object properties but cant get it to work.
What would I have to do to get only the shadwos of my volume to render?
Thanks!
