Ok I'm by no means a newb to the mapping world, but I'm having this problem. I just started mapping again here recently I can't get the model to work. I left all sides caulk except for the top which I applied the water shader too with [ctrl] + [shift]. Now I can only walk on the water but that's it. Also, if I make the entire brush water it says too many fogs. What should I do here?

Yeah water can be a bitch because the ones that came with JA have fog in them to give them that haze effect. I think the idea is to texture the entire brush with caulk_water and then only place the water texture on the top and bottom...although I never got why it has to be the top and bottom to be honest but everyone says that and it works!
