Red glow problems inside Shack (with prints)

Kees_T

The Killer shack has 2 entrances. When the Killer is near them, for example standing in front of the entrace, the red glow won't appear on the inside of the shack. (Any killer)

You can understand by looking these prints I shot:

It happens in any angle:

But once the Killer step a little bit more further, (when he goes to the same height of the shack tile) the red glows appears normally

Happens with both entrances of the shack. Looks like the light of the red glow is beneath the shack's floor, it isn't "curving".
