NvRTX - Self Shadows on volumetric fog


I’m trying out the latest NvRTX release from 5.2. Does the raytracing allows for fog to cast shadows ? I’d ideally like to have the fog cast self shadow, and cast shadows onto other parts of the environment.

Here’s the best I could achieve, this is with r.RayTracing.VolumeFogMode 2. Note how the fog cubes don’t cast a shadow on the ground or on each other,
