Notes

• The tool is designed for simple box nets with a clear, tree-structured folding hierarchy.

• Milk cartons, gusset folds, interlocking structures, closed folding loops, and origami-style layouts are not currently supported.

• The source box net should be flat and planar.

• Object Mode GPU Live Preview does not display the full assigned material appearance.

• A managed Box Net Fold Previews collection may be created for material previews. Do not manually delete its preview objects while the setup is active.

• Apply replaces the editable source object with the final mesh.
