Model Group

Overview

Merges multiple Model parts into one model. The grouped parts go into the same GLB and share rendering and material-assignment workflows. Unlike Solid combine, it does not fuse geometry; it only collects the unchanged parts.

Usage tips

• Use it as the assembly merge point: 部品A(transform済み) + 部品B(transform済み) → group. Groups can be nested, such as lid group + body group → treasure chest.
• Parts may intersect and overlap. The design does not stitch faces or remove internal faces; slight overlap is better than painstakingly eliminating every gap.
• Each part's name survives grouping and is used for GLB identification and animation targets. Name parts before grouping.
• Identical meshes and materials remain shared immutable assets after grouping. Parts stay distinct, preserving appearance and animation targets without duplicate GLB asset data.
• Connecting the same Model directly to both inputs preserves the result but reports a warning about coincident faces and possible Z-fighting.

Common pitfalls

• The boundary should melt together: the Model lane intentionally cannot do this. Use the Solid lane with solid_combine for smooth fusion.
• Only one part should move after grouping: drive that part's model_transform before the group. Trace the graph back to the relevant part; naming makes it easier.
