Plants are currently not receiving shadows. I had the same problem with trees, but was able to fix it with a simple change in SkyrimPrefs.ini but I don't see any similar setting for plants, or maybe I'm just looking in the wrong spot. Or maybe it's a line I need to add. Or maybe it's just a totally separate problem. Regardless, I can't figure out the problem.

Any help?
