Problem with destructible meshes in packaged builds.

YES!!! Disabling GPU skinning fixed the problem for my project.

To find the line in code just hit ctrl+f select current project and search

void USkinnedMeshComponent::CreateRenderState_Concurrent()

This will be in the SkinnedMeshComponent.cpp file.

Then change

const bool bIsCPUSkinned = SkelMeshResource->RequiresCPUSkinning(SceneFeatureLevel) || (GIsEditor && ShouldCPUSkin());

TO

const bool bIsCPUSkinned = true; // SkelMeshResource->RequiresCPUSkinning(SceneFeatureLevel) || (GIsEditor && ShouldCPUSkin());

Then recompile your project, package, done. No flickering.

Thank you !
