OSL: Swirl
OSL Swirl is a simple texture map with a few controls on making swirl textures or swirl masks.
Collision Model & Physics
The Collision Model & Physics rollout in WWMT. Assign a collision hull, create a hull with the Quick Hull function and use advanced features such as the Convexity Hull Wrapper.
Generating LODs
The Level of Detail Generator on the Level of Detail Tools Rollout lets you generate LOD models from the root mesh. The tool will make lower-res versions of your model so that less polygons are rendered in-game when players move farther away.
Incorrect Rotation on World Geometry
Fixed in WWMT 1.867
In earlier versions of the VMF exporter, non-rectangular faces on geometry produce inaccurate texture rotations.
