Step 3: (Important) Go to gmod9/lua/init/ulx_init.lua
Step 4: Open it up and scroll to the bottom. Add the following lines:
_OpenScript( "ulx/ulx_inv.lua" ) -- Adds the ulx_inv Function
Step 5: Load the game and type: lua_openscript init/ulx_init.lua. Say !inv (your name) or (uninv (your name)
Changelog (v2):
1) Removed the extra unneeded lua file (cvar.lua)
2) Added CVAR - ulx_gd_shimmer (default 0) - This makes invisible people shimmer when set to 1
3) Added CVAR - ulx_gd_drawworld (default false) - This will prevent the world model from showing if false
4) Added CVAR - ulx_gd_drawview (default false) - This will prevent the view model from showing if false
5) (Here for reference) Use ulx_gd_inv to set alpha (1-255)
