Mysterious Blue Square
So, I've been playing with the CAW tool for a few days and my first world is coming along nicely (at least for a first try it is) but I have a weird artifact in it that is bugging me. I've searched for others with this problem but no luck. I'm not sure when it popped up since it is in an area of the map that I haven't really concentrated on yet.
I have a big blue square in the water that intersects my "bridge". The intensity changes depending on camera angle but nothing reflects in it and there is no graphical detail in it. It shows up in both the tool and EIG. I've tried using the terrain sculpting tool to see if it affects it, but it doesn't. Changing the water level doesn't do anything either.
Has anyone else seen this or know of a way to fix it? I've attached a few pictures from different angles to illustrate.
Thanks in advance!
