When I enable Substrate in Project Settings then restart I get compile errors resulting in crash.
Are there plans to support Substrate?

Fatal error: [File:C:.…\UnrealEngine-NvRTX_Caustics-5.4\Engine\Source\Runtime\Engine\Private\ShaderCompiler\ShaderCompiler.cpp] [Line: 10582]
5 Shader compiler errors compiling GlobalShaders for platform PCD3D_SM6. Enable ‘r.ShaderDevelopmentMode’ in ConsoleVariables.ini for retries.

Had the same issue. My understanding is that the Caustics branch in general is just not compatible yet with Substrate. Perhaps in 5.6 :)))
