gm_mount2 – Use any source-engine content in GMod
You need to have MSVC 2010 Redistributable x86 installed, or it will not work.
The full version includes spawnicons for some models (several MB). The light version doesn’t, so it is much smaller. But you have to generate the icons yourself.
Annotations for Left 4 Dead 1/2:
Left 4 Dead maps are not compatible with Garry’s Mod. Don’t try loading them – This will only cause GMod to crash.
Why another mounting addon?
You may know the orginal mounting addon and it’s extension for sourcemods. They work well but I wasn’t really satisfied with the way they work and I disliked their messy sourcecode so I wrote up my own from scratch.
My addon directly integrates into GMod and works on dedicated servers which is not possible without many modifications of the old gm_mount addon.
It also can mount Left 4 Dead and Left 4 Dead 2 which is the main purpose of this addon, which took me over 3 weeks, around 2000 lines of C++ code and much coffee to figure that out.
