can anybody help me?
Hey there @M4RKT07! Welcome to the community! Since the error is referencing the shader preprocessor, you were right to check for driver issues initially.
Do other versions of the engine work appropriately? The answer should point us to if it’s a 5.6 feature at fault or an environmental issue we have to solve.
Hi there and thank you for responding
UE 5.5 was also giving me similar errors initially. i would change to DX11 and delete the cache and then it would work. but even that is a hassle and i dont wanna downgrade just because of a driver error.
Eventually UE 5.5 stopped giving me those errors and i could use DX12 seemingly out of nowhere.
Have you got any idea how to fix this?
We’ll have to identify where the error’s coming from, as there are some issues with driver updates across common GPUs right now as is, but there are far more environmental changes.
Does DX11 or Vulcan RHI work for this version?
idk what this is but DX11 doesnt work either
Vulkan is another graphics API and Render Hardware Interface (RHI) supported in the engine. Mostly used for android devices however having it as an option sometimes points to DX specific issues (extremely rarely).
Eventually UE 5.5 stopped giving me those errors and I could use DX12 seemingly out of nowhere.
This makes me think it’s driver related more than anything. I would recommend a clean install of a slightly older version of your graphics drivers to see if there’s any change.
