Unreal Engine Issues and Bug Tracker (UE-209389)

Description

The primary shader crashing is "FVisualizeLumenSceneCS" which I've put in the callstack section, but I think this is more likely a binding problem as I'm also see the following crash with cloud shaders (which compile after the editor loads). Only occurs with r.Shaders.Optimize=0 (note: r.Shaders.ExtraData=1 is required to get the Shader Name, otherwise it is marked "unknown").

Script Stack (0 frames) :

Uniform buffer bound to slot 4 is not what the shader expected:
Bound : Uniform Buffer[FAtmosphereUniformShaderParameters] with Hash[0x00b00100]
Expected : Uniform Buffer[Scene] with Hash[0x008c1f51]

Steps to Reproduce

Go to ConsoleVariables.ini and uncomment:
r.Shaders.Optimize=0
so that optimization is disabled.

Start Development Editor -> TP_ThirdPerson project.

Crash should occur during Compiling Shaders step of editor loading. If skipped, another crash will occur once the editor has opened.

Callstack

Note: This callstack only seems to appear the first attempt to compile shaders. Shader version or another change needs to occur to cause it to appear again.
