help needed with V-Ray (VRay Mtl, Maya Lights)

Hi,

Iīm new to V-Ray and I have a problem I need to fix quickly.
I have to render with V-Ray, so I only use V-Ray materials in my scene.
I use a VRay Mtl with 100% transparency (Refraction Color white, amount 1) as a window glass.
And I use a Maya Directional Light as a sun.
Unfortunately the transparent material still casts 100% shadow, so my sun doesnīt light anything behind the window.

Canīt I use Maya lights, wehn rendering in V-Ray or have I just overlooked something?

Help much appreciated

you should only be using vray lights with vray for best results

Try this:

For you glass Vray material shader go the the Refraction settings and check ON "Affect Shadows."

I was afraid of that. However, I hoped that the other lights still work.
Thereīs no VRay Light similar to the Directional Light, I guess.
Of course, I can give the Directional Light VRay Light Attributes, but that didnīt help.

Yes, this works!
And yes, I completely overlooked this checkbox.
Thanks a lot!
