This question was created in reference to: [RVT - mips [Content removed]
Hello,
I created this question because I didn’t find how to re-open my old case.
We tested some more this problem and we found that:
-
Occasionally some RVT mips have a value of 0 for Normal, color and roughness, which generates either a slightly blurred mirror or black blocks depending on the viewing angle. These blocks blend depending on the camera distance because they are only present on certain mip levels.
-
The bug is also machine-dependent, making the Virtual Texture Pool very small can help but we don’t exceed this pool when the bug appears in-game. it’s completely random, making it very difficult to track or reproduce. Forcing the RVT refresh shifts the problem, so it’s impossible to be sure whether the rendering will be good or not.
We found other peoples having the same problem on UE forums
and more recently a similar [UDN [Content removed] my colleague [mention removed] posted in it to link my previous question and I’m posting here to regroup mine with them and follow everything on one thread.
Thank you,
Bastien Citarella
