Unity light going through walls.
Here is how to fix it.
Shadows are the obvious answer however i assume you are using lite and that s not an option.
Light passing through walls 1.
Hi all i have a basic pb building and in each end of the room the directional light seems to be shining through the walls even though i have shadows set to two sided.
Since you re using unity free put the plane on a specific layer.
That s why shadows exist.
These options have obvious edge cases that can t be easily resolved.
Although you have enclosed the light indirect light from the light source seems to seep through especially on the ceiling and the floor.
Set the point light s baking property to mixed or baked then bake your lighting data using the lighting tab.
Then click on your light click on the culling mask dropdown then uncheck the layer the object is on.
In that case you ll need to be a bit more clever.
You have a point light source behind some walls.

You have a point light source behind some walls.
It s really just a shadow type setting that needs to be set right.
If either of these don t solve.
Now the light will not affect the object.
