After switching over to forward rendering (testing MSAA and performance) my volumetric fog no longer works. I looked around a bit and couldn’t find anything that could tell me why. Does volumetric fog even work with forward rendering?
It works for me in 5.4 (and 5.3) including volumetric shadows. But if I recall correctly, forward shading has not always supported volumetric fog so if you’re on an older version (UE4 in particular) it could be why.
Should also be noted that by default Volumetric Fog is disabled when Shadow Scalability is set to Medium or lower.
Otherwise, not sure what the issue could be.
Thanks. I switched back to deferred, but I will double check scalability next time I test forward rendering. Edit: I’m on 5.1
