In retro games, cutting a 3D model requires manual vertex/polygon editing with game engine-compatible modding tools—older engines don’t support real-time dynamic cutting.
- **Engine Limits**: Retro engines (e.g., N64, PS1) have low processing power, so "cutting" means splitting geometry (dividing polygons, adjusting vertices) for modding, destructible parts, or level design. - **Tools**: Use format-specific tools like Blender (with plugins) or engine editors (e.g., N64’s BMDView).
For modding: 1) Pick a tool for your game’s format (check modding communities), 2) Export the model, 3) Split the geometry, 4) Reimport and test in-game.
