Lithium Unwrap

Lithium Unwrap is in many users opinion the best texturing program. It allows you to texture a model in one of two ways.

Tutorial

Lets start with a tutorial ship Modelled by Max Sterling.

1. Open the file. File ----> Model ----> open
2. Now you'll see a jumbled mess of faces; first we want to assign these faces to a material. We do this so we can begin UV mapping our model.
3. Select all faces by clicking the arrow icon in the tool bar at the top. Then drag a box around all faces you can see; if you can see only some faces (or nothing at all), try zooming in or out by using the magnifying glass icon in the toolbar. Click and hold while moving your mouse up and down to zoom in or out.
4. After selecting the faces, a red box should show up around them. Now click materials ----> modify -----> Mat 0 ----> Assign ----> OK and close the menu. Normally Lithium Unwrap will create a material and assign all faces to it if you dont already have one, but it's good to know this.
5. Now select material0 in the left hand column, expand materials by clicking the + if you have to.
6. "Drag select" all the faces again and now click Tools ----> Uv Mapping -----> Box mapping ----> OK.
7. Now your texture will be slightly more organised (but still a bit confusing if you've never used Lithium Unwrap before).
