Polysoup shadows

Ok so ive been searching for a couple of days and I cant find this anywhere. Can someone please tell me what do I need to edit to fix the poly soup shadow problem i am getting?
Normal shadow (before polysoup) did a light shadow
New shadow (w/ polysoup) is extremely dark and doesnt shadow anything.

I know all this has already been added into tgea but my project is calling for a lowend, so we are using tge but we would like polysoup if we can get it.

Thanks in advance for your help
