Sketchup and Left 4 Dead!?

I am not a major "gamer" per say... but I have been playing Valve games since the first Half Life and Counter Strike. This is not Revit or BIM oriented... but could it be one day? Imagine using an intelligent building information model and importing it into your favorite first person shooter. Talk about experiencing your project... killing zombies enters the workflow of BIM. Could this be the start of BIG (Building Information Gaming)? I coin that term!

Today we are opening the beta of the Left 4 Dead Authoring Tools to the public. It is available as a free download for all owners of the PC version of Left 4 Dead, and can be found under the "Tools" tab in Steam.

The L4D Authoring Tools include modified versions of the same tools we used to produce Left 4 Dead.

Using the L4D Authoring Tools, you may create your own campaign maps, character skins, 3D models, sound effects, and music and load them into the game.

Here's what's included:

Updated version of Hammer, the source level editor
Updated suite of command line compiling utilities
Updated Particle editor
Updated Faceposer
Example maps, common infected, props, and explosives
This release also introduces a pair of plug-ins for SketchUp, a 3D modeling program you may download for free. You may use these plug-ins to create building blocks and props that can be imported into Hammer for use in game levels.
