Did you fix it?
This is my VT config in DefaultEngine.ini
[/Script/Engine.RendererSettings]
r.VirtualTextures=False
r.VT.EnableAutoImport=True
r.VirtualTexturedLightmaps=False
r.VT.AnisotropicFiltering=False
bEnableVirtualTextureOpacityMask=False
r.VT.TileSize=128
r.VT.TileBorderSize=4
r.vt.FeedbackFactor=16
You can try deleting this folders too:
\Intermediate
\Saved
\Binaries
And this folder has shaders and a lot of garbage…
You can delete the files but do not the delete the folders.
C:\Users\Admin\AppData\Local\UnrealEngine\Common\DerivedDataCache
I hope you can fix it
Best Regards!!
