Hello, i have some weird artefacts, i had not it on UE4, but recently i updated my project to UE5.
It appears at some distance. It also disappears for a while then i restart the engine.
It is not depended on post effects.
I use rtx2060.
Are you using lightmass? This almost looks like your lightmap mips are somehow getting corrupted.
I do. But is is fine. It somehow depends on mipmaps, if i disable mipmaps this problem fades away.
Ok, i dunno why, but this was caused by texture streaming.
Ok. disabling texture streaming did not help.
For some reason some textures mipmaps turns into mess from time to time. It happens to different textures and to different mipmaps levels, sometime it happens to mipmpa0.
Is my videocard dying? I mean have no any problem in videogames or UE4, Unity or any other 3d software.

MIPs are not GPU feature, it’s literally part of the texture file. If there’s a corruption, I’d rather point at SSD/HDD. It may be cause during MIPS generation however. You can try to set MIPS count to 0 and increase it again.
You can try re-importing textures that have the issue so it can try to re-generate the mipmaps, if you have issues with the lightmaps then try rebuilding lighting.
I know it is not gpu feature, but mipmap loads to GPU at runtime. Same files was fine in UE4.
Reimporting texture helps once, but then it happens again and again.
Lightmaps and uv are fine.
Maybe report it as a bug and send the project to Epic
I also tried migrating one UE4 project (a simple ArchViz room) to UE5 → some textures, probably lightmaps ones, are destroyed: the ceiling was a basic white material, but in UE5 is totally blue.
Seems like increasing streaming memory pool helped.
Not sure yet.
Did you have lightmaps already calculated when opened the project? Try deleting/recalculating them.
Dealing with the same issues with the corrupted mip maps as well. Streaming Texture size doesn’t solve the issue, nor does building the lighting or texture streaming.
When it does occur, SVT helps, but as it’s preferable only on high res textures, keeps on expanding to other maps in my build as well. This is occurring since the 516.59 Nvidia Game Ready Driver…

Lightmaps are not considered as static asset, so you have to update them from time to time.
As for Bug report, it should be repeatable and there are steps to reproduction necessary. I.e. you need to be able to recreate the issue from scratch.
Hey there. Started having a similar issue in my project a few days ago.
I’ve been working on an environment in UE5 these past few weeks and I only recently (meaning those last 3 days) this problem, which I had never come across. Example: UE5 texture corruption issue - Album on Imgur
Sometimes it’s one texture, sometimes it’s another (from another asset for example). Simply reimporting the texture fixes the problem and the asset looks fine again, but it can happen again in a seemingly random way.
It may be important to note that this has started happening pretty much at the same time that this following error started popping up: Video Memory Exhausted (#### MB over budget). Expect extremely poor performance.
Performance is not that bad (I get 30 fps in a fairly photoreal environment and I don’t need more anyway) but I never got that error until a few days ago.
Graphics card is RTX3070 with game drivers. Just switched to studio drivers today so we’ll see if it happens again after that.
Any ideas?
Thanks.
I still did not fix it.
I’m also have the same issue despite the textures are from quixel plugin inside UE5
the only way to fix it is to restart the enigne … and yes it happens after streaming pool issue or videocard exhausted error messages

same issue, rtx3080 laptop
Same issue here, rtx3080 desktop
RTX2080 having the same issue, is there a remedy for this?
