I have to dig this up, because apparently its still a plague and Im at the end of the project, do I have to worry losing it?
No Vram shortage here, 12gig are more than enough for a scene with only 12x2k textures.
Started to happen on 5.1.1
Its some bug with the engine, all the info I found (and there is plenty but never a working solution) is that it happens on 5.0+ and random, regardless of SSD, HDD, Vram size, mempool, ram, etc, which leads me to conclude its a UE5 issue which epic is not aware of.
