ah ha!
turns out there are no mdls in the game dir by default. I had to extract them from the tutorials ive been reading and moving them into the game root dir in a folder I named models....
then add that folder to the presents.
now I can use add model and I actually see models now.
dont know if this is the correct solution but its a work around.
just wish I where the behavours where now so I can add a custom path for that some how because its blank...want to use the default player_walk behavour
