The BinMapper Window

Textures: drop down menu displays the current texture pool that's available for mapping.

Texture window: displays working texture, vertices and face lines.

Guides: optionally displays grid markings for easier mapping.

Preview: checkbox toggles real-time texture mapping on the model. This is like auto-proof in a paint program.

Join: connect face points that share the same vertices.

Layout: spreads face lines to fit the entire texture.

Reset: allows you to start over without closing the mapping window.

Toolbar Buttons: select the mapping modes. More info here.

Texture Tools: select the mapping tools. More info here.

Note: Mapping coordinates are remembered from session to session after a face has been mapped.
