Yeah HDR is always hell to work with, but makes maps look so much better lol. It looks really good with that skybox too though, hopefully you can figure out why it causes models to glow.
One thing I am a little concerned about basing from the photos is the darkness in some areas, especially the caves. In my opinion large areas that are dark gives the defender so much of an advantage and makes sieging areas very difficult to do, it makes the PvP feel annoying. Might just be a me thing, but I remember it being a huge annoyance on Embassy on the map that was on before the one we're currently on. Just wanted to throw this out here so it's known lol.
