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.
Unity light going through walls.
These options have obvious edge cases that can t be easily resolved.
You have a point light source behind some walls.
It s really just a shadow type setting that needs to be set right.
I am using gaia for the terrain and have the lighting set to afternoon light for those familiar with the program.
Create a unity primitive cube plane etc sized similarly to your wall remove its collider and in the mesh.
Then click on your light click on the culling mask dropdown then uncheck the layer the object is on.
You can simulate this in shaders or use raycasts to see if the light is behind a wall.
Although you have enclosed the light indirect light from the light source seems to seep through especially on the ceiling and the floor.

The layers are the dropdown box in the upper right of the inspector.
That s why shadows exist.
If either of these don t solve.
Since you re using unity free put the plane on a specific layer.
Here is how to fix it.
Light passing through walls 1.
In that case you ll need to be a bit more clever.
Set the point light s baking property to mixed or baked then bake your lighting data using the lighting tab.
