Hiya,

Is it possible to get shadows cast from an object onto a geometry light? I'm using H15.0.397, rendering with the PBR engine.

I have a reflective (chrome) sphere sat inside a box geometry light, and my geometry light is set to use a HDR (rat) of an environment to emit light using a simple material exporting the Ce variable.

I would expect there to be shadows cast onto the geometry light from the sphere, which would then be reflected into the sphere itself. However it looks like the sphere is just reflecting the environment with no shadowing whatsoever.

How could I add in this ability? Do I need to tweak the shader on the geometry light, the sphere, or is there another workflow I should look into?

Any help is greatly appreciated!

Cheers,

Daniel
