How to render VrayShadow element?

[pentool]

Oddly I can't find anything about on how to setup the VRayShadow render element. Nothing on google and nothing in this forum. I find a few here and there, but they don't provide any solution.

1. One object
2. One plane
3. One VrayLight (dome)

Rendered to VFB.

I don't think this is such complicated scene, yet I can't get it to work. All objects have VRay material. Yet, the VrayShadow render element is just black.

Anyone could help me out what is the secret here please?

Thanks!

Is the alpha of shadow element black too or do you see shadow there?
I would also try with like spotlight first. Just to checj that setup is working.

I figured it out. First, the "Store with irradiance map" switch for the light has to be OFF. And second, the plane should not be black color (...DUH!)
