Copies
Standalone flat panels — no 3D assembly. Each copy is its own panel: click one and use “this face” scope to give it its own pattern, then export nests them all together.

Distort

Stretch, taper, twist or randomly distort the solid. Distort follows the Seed and keeps faces flat; taper/twist re-facet non-triangle faces into crystals — they shine on triangle solids (icosahedron, geodesics).

Clamped to the inscribed sphere; each face responds to its own distance and offset from the source.

Mix spread
Uniform — whole lantern
Gradient bottom → top
Gradient around
Mix style
Morph — blend the shapes
Patches — cell by cell
Invasion — pools of B
Front — sweeping seam
Stitched — mended seam
Two full pattern setups: B starts as a copy of A. Mix them with the slider — 0% shows pure A. Morph blends shapes; the region styles keep both patterns crisp and share the face between them. Gradient spreads sweep the mix across the lantern. Faces with their own edits ignore the mix.
