Hi, how can I find all game models?

[Marttt]

I usually get it by L4D/2 Authoring Tools, open hammer, open any map, go to the 'View" tab and open "Model Browser" (don't forget to select the first option in dropdown folder)

I don't remember if these are the correct steps since I'm not with it open now, but should be something like this.

What do you need them for?
Look on my fork of object spawner, there you can find config with the most interesting models for l4d1

I found where all the game models are stored pak01_dir.vpk after unzipping the archive, they can be easily found

there are also 2 packs, second is located at:
