Vray Dome Light color correction and node bugs?

Hello, I have been trying to get into Vray Blender for a while now, and I have ran into couple strange situations, mainly with Vray dome lights.

When I set them up the normal way, everything works, but sometimes I need to do some color corrections on the HDRI. When I add a Color Correction node between the V-ray Bitmap and Light dome node, the output turns into a blank solid color.
I would like to have the option to use nodes to change the appearance of the bitmap, but all nodes that can be connected in between, result in blank output. This does not happen when using bitmaps for materials.

I also noticed similar behaviour with displacement. When I used the UVW mapping, the displacement was showing correctly, but as soon as I switched to tri-planar or tried to correct the map, the displacement stopped working all together.
It seems that certain node patterns result in the bitmap not being picked up correctly.
Is that something I misunderstood on my side, or an actual problem? I attached simple screenshots of the issue.

Thanks in advance.


Hi @tobias_titera ,
You need to manually connect an environment UVW generator like in the image below. Currently we only add a default Environment UVW generator if the bitmap is directly connected to the light output node. I have logged it in our system and we will try and improve it for future releases.

Ah ok, thanks a lot! Quite a simple fix, glad for that.
