just found this lil bug. volumetric fog disappears when the camera is located in a shadow area and looking in the light direction. full config. standard expo volumetric fog. mega directional light (not related).
this issue also appears on a low end config without lumen and megalights with the same shadow cast underneath this overhang kinda section.
also… non volumetric fog seems to be broken. albedo color has no effect. only the emissive color is working.
any insight what i setup wrong would be nice.
