hello friends, i have a trouble when try to using Metahuman Character, i get open the Blueprint of my BP, but when going to viewport the engine stop and after 10 seconds it crash. I don’t know because.

I tried to Uninstall and reinstall the engine, delete the DerivedDataCache folder of my engine, but nothing happens.

Someone have a similar trouble.

Another information’s this problem happens since the first version 5.4, i tried all the updates but nothing.

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] 
Shader compilation failures are Fatal.

Hello, are you using a older Metahuman perhaps? Did you try to open Quixel and add a fresh Metahuman?

Hello @unit23 , not i’m using a 5.4 Metahuman Version created from Metahuman Creator, but this happend until with the demonstration metahuman of Motion Matching Game Animation Sample Project.

After some lot of additional test i discover that my metahuman is loading but the problem is around the Groom of the Metahuman.

Is the Groom that crashes my engine, but i don’t know why
