I've been adding lights in my map, but one thing that has always been a problem is lights going through walls and floors. I cannot figure out how to stop this. Here is an example screenshot. I have a blue light coming from a police car outside, and the blue light is shining completely through the walls, I want it shining just through the two barricade windows. Thanks in advance!

When you create a light, make sure that in the Entity Info window/KVPs that SHADOWMAP in the "LIGHT TYPE" settings is not set to true (i.e., make sure there is no X through it). You will notice once this is false that the light will now "collide" with anything solid and cast shadows.

Hope this helps! Let me know if you need anymore help with lighting!
