hi @motorsep ,
The patch is not needed as its already converted and installed in UE5-main-5.4
5.4
if (SimplifySubstrate && (!Substrate::IsSubstrateEnabled() || CVarPathTracingSubstrateCompileSimplifiedMaterial.GetValueOnAnyThread() == 0))
5.3
if (SimplifyStrata && (!Strata::IsStrataEnabled() || CVarPathTracingSubstrateCompileSimplifiedMaterial.GetValueOnAnyThread() == 0))
the above is the relevant lines converted from STRADA 5.3 to Substrate 5.4
Thanks
