Viewing Alien Swarm Models

ASW Model Viewer - Shield Bug

Alien Swarm assets including models are all packaged into VPK (“Valve Pak”) files and cannot be accessed manually unless they are extracted with a tool such as Gibbed’s VPK Extractor.

Packaged models should be viewable with the Model Viewer but Alien Swarm‘s aren’t. That’s because the Model Viewer requires a proper folder/directory structure even if said folders don’t actually contain any models. Otherwise you’ll get a bunch errors.

Model Folders Dont Exist

To view Alien Swarm models, then, you’ll need to create a whole bunch of empty folders in “C:\Program Files (x86)\Steam\steamapps\common\alien swarm\platform\Models”. That’s a bit of a hassle to do manually, though, so I used TreeCopy to make a copy of the folder/directory structure (but no actual files) created after extracting the “pak01_dir.vpk” file with Gibbed’s VPK Extractor. Like so:

Tree Copy Model Folders

The files extracted from the VPK weigh in at over 500mb, so if (like me) you just want to browse through the models and not actually manipulate them, this is a much nicer solution. To make life easier I’ve created a ZIP file copy of the relevant folder/directory structure which you can download here. Just extract it over your existing “Models” folder and you should be good to go.
