Independent Transform Operators

Relax 

Allows to reduce the stretching the faces of the island. Uses three algorithms.

Panel

- Zen Relax. The algorithm is most suitable for organic objects. - Angle Based. Blender’s native algorithm. Most suitable for the hard surfaces objects. - Conformal. Blender’s native algorithm. Same as Angle Based, but much faster. However, can lead to undesired results if the island is complicated.

World Orient.

Rotate Islands the way they are oriented on the Models. Each method (Organic/Hard Surface) uses a heuristic approach and correctly orients most of the Islands in its area.

Panel

Method: Hard Surface / Organic. The orientation method is suitable for geometry types.
Further orient. Additional turn. Allows you to turn the island to a horizontal or vertical if the island is located at an angle in the model.
Flip By Axis. Allow changing direction of the island after basic orientation. Suitable if needed change orientation from legs to head for example.

Randomize.

Randomize the position, rotation, and scale of the islands or selected vertices.

Panel

Quadrify Islands 

Straighten rectangular-shaped Islands.

Quadrify_Example

Preferences

quadrify_op_props

By selected Edges. Selected Edges will be used and marked as Seams during Quadrify Islands operation. Works only in edge selection mode.
Mark Borders. Mark borders as seams/sharp after Quadrify Island operation.
Mark Seams. Mark seam in case Mark Borders is on.
Mark Sharp. Mark sharp in case Mark Borders is on.
Orient to. How to orient Quadrified Islands.
- Initial. Leave orientation as is.
- Vertical. Set orientation vertical.
- Horizontal. Set orientation horizontal.
Average Texel Density. Averaging the size for the processed islands.
Pack Quadrified. Pack Islands after Quadrify Islands operation.
Pin Quadrified. Pin Islands after Quadrify Islands operation.
Tag as Finished. Tag Quadrified islands as finished.

Tip

Tag Quadrified Islands as Finished to preserve them from unwrapping. It’s recommended to Tag as Finished all manually changed Islands.

Reshape Island

Changes the island’s shape depending on the preset. Here is full information about Reshape Island.

Panel

Selected. Straighten the selected Edge Loops and relax not selected vertices.
U Direction / V Direction. Edges is aligned in the indicated direction.
Borders. Straighten the edges of the island in even lines according to the given parameters.

Match and Stitch

Matching the position, rotation, and scale of Islands. Stitch the vertices together, if possible.

Panel

Tip

Watch the video explaining how Match and Stitch works.

Transform Types

Move 

Move Selected Islands

Info

Buttons of the Universal Control Panel in the Transform type Move represent the direction of shifting.

Transform

Move Increment

The value on which the island will be shifted.

Scale 

Scale selected Islands.

Info

Buttons of the Universal Control Panel in the Transform type Scale represent Points from where the island will be scaled.

Transform

Scale Mode

Axis

Scale. The value of the scale of the island for each of the axes.
Tuner. System that helps change values quickly.
- “D”. Increase by two times.
- “H”. Decrease two times.
- “R”. Reset value to 1.0 .
- Lock. - The Lock mode allows changing values as one.

Units

UV Size. The estimated width of the UV area.
Desired size. The size of which should be set for selected elements relative to UV area.
G. Grab desired size from current selection. Exist only in the 3D Viewort context. Can be used only for 2 vertices or for one edge selection.
Horizontal / Vertical. What mean the Desired Size.

Rotate 

Rotate selected Islands.

Info

Buttons of the Universal Control Panel in the Transform type Scale works as described. Buttons located in the corners rotate the island in the specified direction.

The central button performs the automatic aligning of the island horizontally or vertically. The buttons at the top and bottom align the island vertically. Buttons on the left and right align the island horizontally.
