Geometry with VrayLightMtl and Direct Illum Activated cannot disable Cast Shadows

[Witt3D]

As the title says. Dont know if its a bug or is just on my side.
Also havent test if it doenst work any of the vray properties as "Visible to GI", "Visible in Reflections",..
For sure Cast shados doesnt work here and it starts to work if i check off Direct Illum on the material.
Thank you.

Thanks for the report. I've logged the issue (internal bug-tracker id: VMAYA-12628 ). As a workaround, you could disable the "Primary visibility" instead, however, this would hide the object as well. If you need the object as well, you may have to render it separately (via a self-illumination pass f.e.).
