Clear Sky - Light error with fire anomaly

[argosurvivors]

Describe the bug
In the map 'Military' there is a house with a fire anomaly. This fire confuses the render and it makes weird direction of lighting inside the next room. The light is glowing like there are no walls between rooms. This error happened to me with DX10, DX11 and Open GL.

To Reproduce
Steps to reproduce the behavior:

1. Start the game
2. Go to Military level in the house with a fire anomaly and watch the light in another room
3. See error

Expected behavior
Most of the light should be contained inside the room.

Screenshots, videos

I suspect that this may be the error with position or direction of the spawn element of the fire anomaly.
The flames are stretching through the roof and might be also getting through the walls. Though somehow this does not effect the original engine.

I did a loot of work on the MSAA OpenGL around the lighting, u can try this branch #1986

I have tested the latest version, render is beautiful with well done reflections and contrast between matte and glossy but somehow light still passes through object in this house.
