Hello guys, I have a point light between two walls and the light goes through the walls (like the light affects other meshes even they are behind the wall), how can I disable it?

You can exclude/include lights per mesh with light.includedOnlyMeshes or light.excludedMeshes to ensure it will impact only what you need.
