I have success with this:

Edit DefaultEngine.ini

[/Script/Engine.RendererSettings]
r.GenerateMeshDistanceFields=false
r.AllowStaticLighting=true
bEnableVirtualTextureOpacityMask=True

If you are using MetaHuman, install this plugin before to add the characters in the project:

One more think, after you change the DefaultEngine.ini, delete DerivedDataCache folder.

hello friend, i have a problem very similar but it is only when try to using Metahuman, my engine Crashed and say that it is because a shader compilation error, after that i tried delete the DerivedDataCache follder, enable de Metahuman Plugln but nothing do a change.

You have some Idea about?.

This is my Erro Log:

Fatal error: [File:D:\build\++UE5\Sync\Engine\Source\Runtime\RHI\Private\PipelineStateCache.cpp] [Line: 437]
