this keeps happening, not at any specific trigger.
It is just some billboards have turned white and also some landscape texture layers… This is UE5. It has happened with lumen turned both on and off.
Anybody got a clue?
Hey there @BIGTIMEMASTER! Cool scene you’ve got brewing there.
Are all of those trees that are distorted of the same material type?
Does this only occur after being in editor for a while, somewhat randomly?
Generally when I see foliage go pure white (or white with static) is when VRAM runs out and starts having errors while trying to catch up.

thanks for the hints.
So upon restarting editor, that brings things back to normal. Did I have it open for a long time when it happened? I didn’t think it was very long, but I lose track of time…
It was somewhat random, like each time it happened it wasn’t after something obvious. Just moving around in scene and blam.
About VRAM running out - I have not got any texture pool size exceeded messages in this scene (it’s only a couple materials at play so far). However, restarting editor to fix the problem seems to suggest you are correct. Is there any output log that might indicate VRAM usage and if there is a problem? My computer well exceeds minimum specs for ue5.
update: actually all those foliage and grass textures were set to 4k and there is like 50 of them so it could easily be running out of vram
There’s a couple of possible hints, the texture streaming pool doesn’t have to overflow for you to be using too much VRAM at once. You may have enough, but as you said 10,000 calls for 4k textures is a ton, instanced foliage reduces that cost a good bit but definitely still enough to batter even a decent graphics card. Add that on top of all the normal editor shader business going on in the background? It’s feasible. You could do some profiling and see if it starts to spike after an hour or two in editor.
Take a look at the GPU insights in the profiler and see if anything looks extreme
