I have a fireplace with a fire particle system, however when it’s placed, for some reason the light on the particle system is shining through to the other side of the wall. I have tried the two sided lighting/shadow but still doesn’t work. Also tried building lighting on “production”.
Below is the image of the fireplace with the particle system. The second image was too large for this post, this is the other side of the wall: http://imgur.com/a/mHsZZ
