Hi @Sherry_Xxx ,
I think you probably should have loaded the EPIC GPU Lightmass patches
EpicGPULightMass Landscape 5.3.2 Patch/README.md
This will fix the picture above. The patch you have loaded is for baking using Nvidia code directly on the GPU.
Epic GPU Lightmass require at least a Nvidia RTX2010 onward or AMD 5000 and uses direct x 12 shaders 6.1 extensions and Windows 10 NOT Windows 11(eleven)
