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.
Attachments & Particle System UI
Attachments are points on your model where you can attach extra models and particle systems (guns, sprites, etc). This page details both Attachments and Particle Systems since the Particle System controls are also in the attachment rollout.
