Unity Light Goes Through Walls

The real solution would be to create walls with actual depth so it gives the shadow bias some room to work.

Unity light goes through walls.

Shadows are the obvious answer however i assume you are using lite and that s not an option. My level has high walls all around it and what i want is for the 1st person controller to just bump into the walls without going through it i created the level before i heard you need to tick the generate colliders so i ticked that doesnt affect the level thats out it will make colliders but i will have to start it all over again. For his situation and scene what worked best we thought was to simply set a floor2 layer on the other side of the wall and disable that layer for that light. Since you re using unity free put the plane on a specific layer.

Then click on your light click on the culling mask dropdown then uncheck the layer the object is on. That light should not affect that hallway at all anyways so it works perfectly. That s why shadows exist. You can simulate this in shaders or use raycasts to see if the light is behind a wall.

Now the light will not affect the object. Although you have enclosed the light indirect light from the light source seems to seep through especially on the ceiling. In that case you ll need to be a bit more clever. Light going through wall unity answers unity is the ultimate game development platform.

Otherwise lights will go right through the backfaces by default. Published on nov 2 2017 you have a point light source behind some walls. These options have obvious edge cases that can t be easily resolved.
