Pixel Unwrapper

Key Features:

• Pixels Per Unit: Allows setting a desired Pixel Density to maintain consistent pixel size across the model. This density is used by the Unwrapping operators and the Rescale Selection operator to determine UV scale.
• Create Texture: If the model doesn’t have a material with a texture, this button creates them and sets the Texture Interpolation to Closest.
• Unwrapping Tools:
  • Unwrap Basic: Performs standard Blender Unwrap operation but scales the result to match Pixel Density.
  • Unwrap Grid: Detects a grid of quads in the selection and maps each row and column to whole pixels, applying Pixel Density.
  • Unwrap Extend: Unwraps unpinned faces, similar to standard Blender Unwrap.
  • Unwrap to Single Pixel: Maps selected faces to a single pixel on the texture.
• UV Editing: Some UV operators can be applied while preserving bits of texture already painted. Includes Destructive mode and Preserve Texture mode.
• Folding Tools:
  • Rescale Selection: Rescales the selection to match Pixel Density.
  • Selection to Free Space: Moves the selection to a free bit of UV space, copying texture pixels to the new location in Preserve Texture mode.
  • Randomize Islands: Moves each island to a random position on the UV map.
  • Repack All: Repacks all islands onto the bottom of the UV map.
