V-ray GI Renderpass is glowing around corners

#1

Hey there,

I’ve an Issue with my GI Renderpass in V-ray, it creates an weird glowing around the corners.
This happens in Vray GPU & CPU with LC & BF. (without GI its not visible)

I’m using the latest version of Vray & 3ds Max 2022.

In the beautypass its not always visible but when I disable Cast Shadow for a Light this is also visible to the beautypass.
This glowing is also appearing when I switch over to Composite/Backtobeauty in the VFB.

The Material have no reflection.

any advise to workaround with this ?

  1. Lightning
  2. Beauty with cast shadows turned on
  3. GI Pass
  4. Beauty with cast shadows in VFB (compsite/backtobeauty)
  5. Beauty without Cast Shadows.

why use light cache for primary

#3

This happens not only with Lightcache.
It happens in any combination of the Gi engine.

It looks like an inverted AO…
