What is the unwarper?

The unwarper seeks to automatically straighten a texture with wavy or warped patterns. In addition to this it automatically identifies patterns within the texture. When attaching it to a default mutation node the pattern will automatically be maintained as you grow to your chosen resolution.

Typical use cases

  • Straigthen faulty and warpy scans
  • Automatically detect patterns in images


Node requirements

Input Type: Bitmap/Material

Output Type: Bitmap/Material


Step-by-step guide

  1. Connect a warped bitmap or material to the pattern unwarp node
  2. Press identify pattern in the property panel
  3. The node will analyse the image and present you with a repeating grid
  4. You may right-click the grid to gain access to control points to tweak if they are slightly off
  5. Once satisfied, press unwarp, or click the execute button
  6. The grid will straighten, and simultaneously unwarp your image





The pattern unwarp node begins by looking for the smallest possible patterns, in doing this it can find groups of pixels that look like a pattern to it, but to a human is clearly wrong. When this is happening manually indicating the pattern can help, this also significantly improves analysis time.

  1. Connect a warped bitmap or material to the pattern unwarp node
  2. Untick the auto definition checkbox
  3. The image will be outlined in an adjustible white grid, position the grid over a repeating element
  4. Once positioned, press identify pattern in the property panel
  5. The node will analyse the image and present you with a repeating grid
  6. You may right-click the grid to gain access to control points to tweak if they are slightly off
  7. Once satisfied, press unwarp, or click the execute button
  8. The grid will straighten, and simultaneously unwarp your image
