Hi!! first of all, I'm not new in mapping, but after 5 years of doing maps for HL, I'm finishing my MOD and I've done a map with fake fog made with Illusionaries, and it looks very good, except for the fact that it behaves like water, I mean, if I walk into the illusionary it works like water, I can swim, and I sunk after a while, this problem also blocks monsters ( in the consloe appears a "MONSTER STUCK IN WALL : ERROR AT LEVEL DESIGN" message ).
Anyone knows what could cause this ?
Thanks in anticipation.
