Loading cooked shaders in editor is broken

Loading cooked shaders in editor is broken

Description

Issue was traced to CL4018267. Shader hashes are not preserved during cooking anymore. This is failing the check in

void FShader::Register()
{
FShaderId ShaderId = GetId();
check(ShaderId.MaterialShaderMapHash != FSHAHash());
-----> check(ShaderId.SourceHash != FSHAHash() || FPlatformProperties::RequiresCookedData());

 

NOTE: This bug should have been caught by [Link Removed] but it seems the tests uses a material cooked in a previous version that was preserving the SourceHash.

Steps to Reproduce

Load the project from the GDrive location in version 4.20 ([Link Removed])

Click on the Twinmotion button

Open the 'tm' file in the same folder that the uproject
