Merged your post into this thread on the issue, others are also experiencing it.
There is another thing worth trying:
prop $ConfigGroup SsaoEnabled false
@Bluebellflora Following those steps did get rid of the shadowy boxes under my sims, but the legs of my male sim are still shadowy for some reason, while my female sim doesn't have the shadow...
I'm a little embarrassed... it looks like the shadow on my male sim was actually just a sun tan. I pressed shift and clicked on my sim, then "sunbathing options," then clicked "no tan," and his legs went back to normal. My issue is resolved!
I'm having the same issue as everyone else. I haven't tried the solution yet, but if turning off SSAO gets rid of the box, does it affect anything else in the game, like shadows that are supposed to be there? Thanks for all the help.
