We have recently switched over our render elements to fully use the capabilities with exr 2.0. We are now rendering with the VRayOptionRE render element. Now we are getting infinite values in our zdepth in areas of artifacting.
it might be related to embree. Try switch it off and see if it helps. Also clamping zdepth might help.
The Embree Solution seemed to work the best. Do you know what this is? I also didn’t remember seeing this. Another solution i found was creating z catchers for underneath the geo. This is a method normally working for edges not sure why it works here too.
Thank You
I believe I reported this bug too, its a limitation of the embree code.
