Okay, ya I figured to just use the renderflags for depthhack and noshadow and I don't really care for weapon bob at the moment so it is ok having that short coming. However for DP the .effects flags don't seem to work on weapons, so I've opted to just use the renderflags ones.
Of course now the biggest short coming of mine is handeling hiding it when chase_active is 1, but I can of course do that in one way or another on my own.
