V-Ray 6 - GI and Light Mix Render Elements looking completely different after upgrading from Vray 5.3
TLDR: I created the scene in 3ds Max 2022 and V-Ray 5.3. After installing and rendering with V-Ray 6 my render elements started looking drastically different. I didn't change any settings when migrating. The largest discrepancies are in the VRayGlobalIllumination pass and VRayLightMix passes, but the RGB looks the same. The VRay 5 images are the results from final bucket renders, and the V-Ray 6 elements were IPR renders. The discrepancies still show up when bucket rendering in V-Ray 6, but the GI pass is completely black instead of just darker. Additionally the Self Illumination pass from the light-mix element does does not render the light cast on nearby objects.
After encountering these discrepancies I re-installed V-Ray 5 to see if I could I have accidently changed some setting, but I got the correct results. I then re-installed V-Ray 6, and the discrepancies returned. With V-Ray 6 still installed, I tried opening an entirely different scene I had made with V-Ray 5, and the render results were the pretty much the same as they were in V-Ray 5.
The attached link shows a comparison between elements from V-Ray 5 and V-Ray 6. The V-Ray 5 results show a much brighter GI pass, and lighting passes that contain more lighting detail. The V-Ray 6 results show a darker GI pass with almost no diffuse information and the light mix passes appear to be lacking indirect illumination/bounce light resulting in much darker shadows.
Are these discrepancies part of the new update or did I accidently change some setting that is causing these passes to look different?
Thanks in advance for your insights and help!
