Unity Light Bleeding Through Walls

When you then go into the room without light you can see on the edges of the walls the light from the room next to it is leaking in.

Unity light bleeding through walls. So i have come to the conclusion that unity just cannot handle walls. Shadow maps are a kind of fickle technology. Pixel lighting and only works if you have unity pro. No matter what setting i play within unity i just cannot seem to get rid of the light bleeding leaking.

Is there something i can tweak to fix that. The rooms themselves consist of just paper thin 1 sided polygons since it s all meshes arranged in random arrangments and no bsp geometry. Position these to block any light leaking through the bottoms of walls. No that s not it at all.

And even with real time shadows light still passes through walls which you can see if you have the shadow strength less than 100 eric. I am having a strange problem with light bleeding through my meshes and causing light lines in the shadows see this image it was working great press j to jump to the feed. Press question mark to learn the rest of the keyboard shortcuts. Here in the screenshots i have an apartment scene.

You can use real time shadows with pixel lighting but that s an additional option not something inherent in vertex vs. You can see a little bit of the light from the other room bleeding through the walls and brightening the shadowed parts a little on the other side in the corners. It will pay dividends to learn how they work what the settings do and how to work around problems like this. This is a bit problematic for me as i have a ventilation shaft making noise on the other side of a wall.

It is airtight and i have a lamp in some of the rooms.
