So for my entry into the 2017 mapping competition, I've made a refracting glass texture. I'm having an issue were the laser in my map doesn't show on the other side of the glass only if the laser is passing through the glass. If it's not passing through the glass, it shows. Is there a way around this or is it just an inherit flaw with the engine? Thanks.

This is probably a bug with the engine, the overgrown glass windows in BEE2.4 (which are cracked) have this same issue.

I had a similar issue and what helped me was I made it a func_brush, although it helped me only halfway.
