Place it just behind your wall so that it blocks the light from leaking out.
Unity directional light bleeding trhough wall.
In some situations normal bias can cause an unwanted effect called light bleeding where light bleeds through from nearby geometry into areas that should be shadowed.
I was wondering how i could go about culling the lights so they no longer shine through walls.
To help users navigate the site we have posted a site navigation guide.
If a light is next to a wall on one side you can see it on the floor on the other side.
That s why shadows exist.
Create a unity primitive cube plane etc sized similarly to your wall remove its collider and in the mesh renderer properties set it to shadows only.
Shadows are the obvious answer however i assume you are using lite and that s not an option.

I believe this has something to do with culling masks or light culling.
You can simulate this in shaders or use raycasts to see if the light is behind a wall.
These options have obvious edge cases that can t be easily resolved.

In that case you ll need to be a bit more clever.
This is caused because the use inverse squared falloff is set to on by default forcing you to have to use way more lights than whats needed or to set it s value far outs side acceptable values.

Any help is greatly appreciated.
