So I'm trying to make a window with the models woodwall030b_window02a (frame) and woodwall030b_window02a_bars (inserts). The frame shows up as a prop_static in all instances but the bars will not as prop_static, prop_physics or prop_physics_multiplayer. They will show up in when they are prop_physics_override but get the same error as othe physics props:Can't create physics object for models/props_wasteland/woodwall030b_window02a_bars.mdl. The flag force server side doesn't seem to help either. Any ideas?
