Color Groups & Grow/Shrink/Loop Select
Color groups (F1–F12)
Twelve color swatches, only shown once a created topology exists — the Loaded Mesh's own selection is binary, so there are no color groups to pick between there. Click a swatch (or press its F-key) to make that color the active selection group; the active swatch gets a white border.
*Note: Color selections will be used in future versions of the software for isolating UV island creation.
Grow, Shrink & Loop Select
Available as soon as any mesh is loaded, and act on whichever mesh is actually on screen — the created topology when it's showing, the loaded mesh otherwise.
- Grow — expands the current selection by one ring of adjacent faces. Disabled with nothing selected.
- Shrink — contracts the selection by peeling off its boundary ring. Disabled with nothing selected.
- Loop Select — a one-shot action, not a toggle: select two adjacent faces by hand first (their shared edge sets the loop's direction), then press this to walk the rest of the ring. On the loaded mesh this follows quad edge flow and stops at triangles or n-gons.
