I really want to use level 1 cascade on my directional light because i love the soft, undetailed shadow it gives the scene, and the performace. It looks realy nice except for one major issue.
Inside interiors the light leaks through the walls and celings, ive messed around with shadow bias settings but nothing gets it close enough without causing the black lines over everything.
Is there some way i can mimic the soft shadows of cascade 1 and not have light leaking? (performance is a big thing for me, so im running regular shadow maps)
