No, not using light propagation volumes. Dynamic Inset Shadows are disabled. Didn’t change Shadow Bias / Slope Bias. I’ve tried these things before when encountering this, except for propagation volumes, and it didn’t work. It doesn’t always occur either, whether in an empty project or a template (3P or 1P shooter, and ArchViz).
I had mesh distance fields disabled and it was a problem, and after enabling ‘Generate Mesh DFs’ it is still there. I moved both the directional and skylight actors to the sun side of the meshes, and the result was the highlight or light wrap problem changed sides while staying at the top edges. It is one of the most bizarre problems I’ve encountered thus far from all the things I’ve tried.
