trying to learn interior

[vpii]

Just playing with Kray for fun of old model from years back. How do I get rid of the dark shadows where ceiling meets wall at top of image? I tried alot of things but so far I am missing it.

I rendered a 200 frame test and was getting about 2 min per frame at 720 width. I have errors in the model but just doing this to learn and test speed.

Are you using pathtracing in the corners to get rid of lightleaks? If you use only 1 try 2-3 to get more lightbounces.
