Random texture files are going corrupt. I will be doing whatever and notice crazy artifacts that look like mixed up data all across maybe a normal map. I haven’t been editing or even really interacting with these files when I notice the issue.
Started happening maybe a month ago and pops up every few days with a seemingly random file. The other day it was a HDRI used in the skylight.
Is there a way to reprocess these without pointing to the source file? Sometimes they are a part of downloaded packs and I don’t see a way to reimport them? What could be causing this?
I am using regular, non-virtual, textures wherever possible. No nanite (explicitly, maybe a mesh was auto without knowledge). Using raytracing, yes, Lumen usually, unless I need to switch to standalone or Pathtracer…
The problem does seem to go away randomly as well, closing and relaunching sometimes helps.
Could it have something to do with any background caching processes, or my GPU going bad? RTX 2080 super
If there are no warnings in the log file, then it’s possible your hard disk or your GPU RAM or your regular RAM or your motherboard is having trouble. Hardware isn’t perfect
That might have done it, but I can’t be sure, because I restarted and the material now appears correct. That said, I checked the console and indeed, it was looking for a virtual texture, after converting, the message cleared out.
Just now, I tried converting the texture back to non-virtual and the message fails to reappear. The param2D is set to use virtual textures tho, so maybe the error will kick in a little later. I don’t think this would be a problem with other actors like Texture Cubes piped into SkyLights.
Hmmm, how are you getting that data up top? I recently started switching scalability to keep performance under control but have not seen those numbers in my UI. “Show Stats” seems like it would have done it?
So weird, here’s another one from today - have not edited the bitmap at all, haven’t opened the blueprint or material or mesh. Reimporting it fixes the issue… maybe I have faulty memory or something… I did just install another 64Gb a few months ago. I don’t know enough about hardware or cached data to have a clue as to whether that could be a part of it.
This is weird, so you got 64Gb ram, but how much is windows giving to the graphic card?
What about the configuration for unreal? Like ram for virtual textures…
96Gb of RAM with 56 for GPU, although my dedicated GPU memory (8Gb) maxes out right away, even when scalability is set to low on minimal scenes with only a few actors and textures.
