Hi everyone. I’ve been working on this scene with two metahumans and some heavy geometry imported from Maya. I’m using nanite to make the meshes workable and I’ve had no problems so far. However, sometimes when I load the scene I find either the Metahumans or the enviornment has this weird glitch texture on it.
I’ve loaded it on a higher spec machine (Threadripper 3990x w Nvidia A6000) and the issue seems to disappear. Same 500gb portable SanDisk SSD. My current work around is to restart the scene which seems to fix it but after a while it just comes back.
UPDATE:
I found that this glitch is changing the material of the object only, not the mesh itself. it seems to also be an LOD issue despite having them turned off.
Seems like a reflection or file corruption of some kind.
Next time it happens set the editor up to look at all the different passes to try and spot when/where during the process the specks are added to the scene.
Based on that, check the appropriate model texrure first to make sure all of the textures are a ^2 file size and have the correct compression values.
Assuming the files all check out, the next step is to verify engine files to make sure nothing is corrupt/damaged.
While at it you may want to also run
chkdsk /f
On the next startup
And after
sfc /scannow
If either finds issues, then you may need to swap HDD/SSD. For that you should consult your drives s.m.r.t. reports - if its failing it should be obvious or just about.
Oh, while at it. Ensure you have all the latest drivers on everything, mostly gfx here it would seem, but if the tests came back reporting damaged files it could also be caused by the drivers or the mobo settings/bios.
Another possibility is the portable drive itself.
Unreal doesnt do well with top speed m.2.s so running a project from a removable drive seems edgy in principle…
