I’m getting these weird blocky lines on my final high-res render. It seems to be the same problem as this older post here:
I tried all the things there but what I seemed to figure out was, when I turn the HDRI Dome Light Off and use sunlight instead, the lines go away. So I’m thinking that was it but don’t know how to fix this.
Maybe there’s a setting I’m not aware of. I wanted to keep the HDRI and not change the image since this exterior light vibe is the one that the client likes already.
I assume this is supplied by VRAY - if so, these are edited by VRAY. You could check that there is no banding on the actual HDRI to start with and is it 32 bit color?
Also, try a few other HDRI’s to see if that fixes the issue.
When I ran it just now with SU v2022 on Mac with V-Ray v5.20.20 I couldn’t re-produce the problem. Personally, unless it’s affecting many views, it may easier to do some some adjustment in post-production to fix those lines. Also have you tried resetting to default settings for everything except the Dome Light?
Here is my test render with HDRI (missing bump maps etc that are pathed to your local drive):
