But this models working on css this game is on hl2 engine yes? So why not work on gmod 9?
CS:S uses EP1 engine (2006 update to HL2 engine, adding stuff like phong shading) whereas Gmod 9 still uses the original HL2 engine from 2004.
Gmod 10, however, uses the Orange Box engine, dubbed Source Engine 14.
