Return to default Shader Instructions:
For all who applied the custom shaders.zip to your launcher install and wish to return to defaults.
Delete your shaders folder and verify your files to re-install the 5.4.3 hotfix shaders
you can use the recalculate shaders all command just to be sure and also clear your deriveddatacache in your project folder and also in AppData\Local\UnrealEngine\Common\DerivedDataCache
UE5.4.3 Vanilla Launcher:
However @VictorLerp I’m having issues after updating to UE5.4.3 with instanced stereo. Are you sure the issue is actually resolved?
I actually pulled the CL that was listed as the fix and copied UE5.4.3 shaders into a repo to do a branch comparison and it “feels” like it just didn’t make it into UE5.4.3 as there are tons of diffs and missing conditionals.

I’ve completely uninstalled UE5.4.3, deleted my DDC and re-installed from scratch and below are my findings. I’ve yet to test mobile yet but once I do I’ll also update the below with those findings for mobile multi view on vs off.
Forward Rendering + instanced stereo (shadows broken in left eye)
Forward Rendering - instanced stereo (shadows working normally)
Forward Rendering can only use CSM
Deferred Rendering (VSM) + instanced stereo (shadows working normally)
Deferred Rendering (VSM) - instanced stereo (shadows working normally)
Deferred Rendering (CSM) + instanced stereo (Shadows broken in left eye)
Deferred Rendering (CSM) - instanced stereo (Shadows working normally)

You can use the above shader patch if you need instanced stereo in forward rendering or mobile multi view and do not need the VSM deferred rendering fix. If your on deferred with Virtual Shadow maps please do not use these shaders as they will create an artifact regression. I’ve also updated the github with the branch containing the fix.

Summary:
VSM seems to have been fixed while CSM remains broken in the left eye if instanced stereo is enabled.
