Tip

Watch the video explaining how Stack works.

Stack

Collect Similar Islands on Stacks.

Properties

Stack

Move Only - Don’t fit Islands. Just move to the same position.
Stack Offset - The offset value. Can be used for preventing auto merging the UV vertices.
Unstack Direction - The Direction where the island will be shifted.

Unstack

Shift Islands from Stacks in a given direction.

Stack Mode

Panel

Global Mode. Collect all Similar Islands on Stacks.
Selected Mode. Collect selected Similar Islands on Stacks.
Simple Mode. Collect selected islands in the stack, with no respect for their topology.

Stacks

There are 3 different types of Stacked Islands. You can select all of them in this panel.

Primaries

Primaries this is islands which detected as a better instance. The position and the topology from Primaries will be translated to the Replicas. The island is defined as Primary if its position is closer to the center of coordinates, and the distortion of topology is less compared to other similar islands.

Replicas

Replicas are islands that have the same topology but were not chosen as Primary. The position and topology of the Replicas will be changed in the process of Stacking.

Singles

Singles this is islands that have no similar islands.

Stacks Display

Similar

Copy / Paste System

Copy - Copy parameters of selected Islands/Faces and save them.
Paste - Paste the parameters saved earlier to selected Islands/Faces.
