This week we finished off texturing our bowling pin model in Blender and then imported it into Unity to use in our game.

UV Unwrap

We started by loading our existing bowling pin model with seams already marked.

The process of unwrapping a 3D model is similar to peeling an orange and pressing the skin flat. The seams we marked are like cuts in the orange’s skin. When we peel it, the pieces between the seams come out separated.

To unpeel the model we entered Edit Mode (TAB key), selected the entire model (A key) and chose UV Unwrap | Unwrap from the Mesh menu. Notice that we don’t see impact of this until we switch to the UV/Image Editor

Switching to UV/Image Editor

Our main panel is normally in 3D View mode. To start working with our texture we click on the icon to the left of the menu options and choose “UV/Image Editor”.

When we change mode we see a flat image with our model split apart and spread out into flat sections. Each of these sections represents a part of our model between a set of seams.
