If I try to open this one level, it crashes when its almost done opening. Anyone know what the fix may be?
Assertion failed: false [File:D:\build++UE5\Sync\Engine\Source\Runtime\RHICore\Private\RHICoreShader.cpp] [Line: 59] Shader attempted to bind uniform buffer ‘FTranslucentBasePassUniformParameters’ at slot [Name: SceneTextures, Slot: 8] with hash ‘159911720’, but the shader expected ‘OpaqueBasePass’ with hash ‘274269473’.
Hello there @SOLDIEROSCAR!
Your error log suggest a shader conflict, like UE is trying to bind TranslucentBasePass while the compiler is expecting OpaqueBasePass. There have been similar cases in other threads, usually tied to a cache issue.
Considering that, the first step would be to close UE, and clear out folders DerivedDataCache, Intermediate, and Saved from your project’s directory. After that, re-open the engine, and allow shaders to rebuild from scratch.
If the issue persists, you can also try switching between DX11 and DX12 during your tests. As well, make sure you resave any translucent materials or material instances used in that map.
You can also test migrating the affected assets into a blank project, in order to rule out specific conflicts with your scene. Hope this helps!
