I created these environment models to add detail to my Deep 6 levels that I couldn't add with brush work alone. I used exported brush work from Hammer as a reference for most of these models, this ensured that they were the correct scale when It came to importing them into the game. Each has had it's lighting baked in Max to apply some quick detail, with the intention of handing it onto a texture artist or of creating a skin for it myself at a later date.
All the models were created in 3dStudio Max.
