Editing UVs

After unwrap, you will likely need to arrange the UV maps into something that can be logically textured or painted. Your goals for editing are:

  • Stitch some pieces (UV maps) back together.
  • Minimize wasted space in the image.
  • Enlarge the faces where you want more detail.
  • Re-size/enlarge the faces that are stretched.
  • Shrink the faces that are too grainy and have too much detail.

With a minimum of dead space, the most pixels can be dedicated to giving the maximum detail and fineness to the UV Texture. A UV face can be as small as a pixel (the little dots that make up an image) or as large as an entire image. You probably want to make some major adjustments first, and then tweak the layout.

Face Mirror and Rotate UVs

The orientation of the UV Texture is defined by each face. If the image is, for example, upside down or laying on its side, use the Face ‣ Rotate UVs (in the 3D View in Face Select mode) menu to rotate the UVs per face in 90-degree turns.

The Face ‣ Mirror UVs tool mirrors the UVs per face, which flips the image over, showing you the image reversed.
