Weird light and dark buckets visible in rendering

[LionHeart1985]

Hi!

I was rendering this scenery with CPU and i got weird buckets visible in my final images.

It´s strongly visible in the "Lightning" render element, so i´m putting this into this post as well.


I´m using Windows 10 with the latest Updates, Sketchup Pro 2019 V19.2.222 64-bit and V-Ray Next 4.00.02
Also my graphic card drivers are always up to date.

My machine works with an AMD Ryzen 1920x / 32GB DDR4 / GeForce GTX1070Ti

No Antivirus tool is running except the Win 10 internal one.


The only light source in this scenery is a 8K HDRI, Sketchup Sun is turned off and i was using the autoexposure function.


I hope you can help me out to get rid of these buckets because it´s nearly impossible to remove them in post production.


Thanks, Walter

---UPDATE---

The problem seems just to show up while using this specific HDRI.

I was changing the HDRI file to a different one, added Sketchup Sun, turned off autoexposure and it worked quiet well.

Hi LionHeart1985

Glad you have managed to resolve the issue!

However, would it be alright if you send us a sample project where the issue is reproducible with the HDRI so we can investigate in detail? If so, please send us an archived copy (Extensions > V-Ray > Pack Project) via email or a file-sharing service of your choice to support@chaosgroup.com
