Are L4d2 models different from normal source models like hl2?

[Jackthemaster]

I'm trying to use l4d2 weapons in gmod, but they are always invisible. Why?

[mvr]

They are not the Same model type

Either do a .vtx copy and paste fix or use gm_mount2 that does that ingame for you.
I'd only recommend the former in case of any source game other than gmod.

You could download this: [url]http://www.mediafire.com/?juy2odzxnxh[/url] then extract it into steamapps/username/garrysmod/garrysmod/addons/Left 4 Dead content/models then run the .BAT file, careful though because if you have any hexed models in there you need to copy the .dx90.vtx into a .vtx file because the bat removes .dxsworxbox.vtx (dx = dx80 & dx90, sw = software?, xbox = Xbox stuff)
