SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? AI-generated vehicles are the hardest 3D category: flat panels, sharp edges, and symmetric bodies expose every mesher flaw, from smoothing artifacts to melted rear ends. This Skill raises the success rate by enforcing multi-angle reference images, picking the right generation backend, and adding an optional detail-texture pass to recover panel crispness. ## Core Features & Use Cases - Multi-angle reference generation: Pass up to four view images via the imageUrls array so the mesher produces consistent front, side, and rear geometry instead of a melted back half. - Backend and polycount selection: Choose between hunyuan for curved vehicles and trellis for hard-edged designs, with polycount targets from 1.5k tris for distant scenery up to 60k for hero showpieces. - Scene wiring: Instantiate the generated .glb as a VehicleBody3D with wheels and collision for player cars, or as a lightweight MeshInstance3D for background traffic. - Use Case: A user asks for a player race car for a racing game; the Skill generates a multi-view reference, produces a 25k-tri mesh, imports it to res://assets/vehicles/, and wires it as a VehicleBody3D with a box collider. ## Quick Start Ask your agent to generate a sleek red Formula 1 race car with front and rear three-quarter views and wire it as a drivable VehicleBody3D in the main scene.

Frequently Asked Questions about vehicle-model

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate a 3D car model for my game with AI?

Generate a multi-angle reference image first, then call summer_generate_3d with kind image-to-3d, passing up to four view URLs in the imageUrls array. Import the resulting .glb and instantiate it in your scene as a VehicleBody3D or MeshInstance3D.

Hunyuan vs Trellis for hard-surface 3D generation?

Trellis tends to preserve sharp panel edges better, so try it first for clean hard-surface designs like spaceships and F1 cars. Hunyuan is the default for general quality and handles organic curves like muscle cars and boats better.

Why does my AI-generated vehicle have a melted rear end?

A single front-view reference gives the mesher no information about other angles, so the rear collapses. Pass multiple views through the imageUrls array; writing multi-view phrases in the prompt text has no effect on the 3D tool.

Can I assign a .glb file directly to MeshInstance3D mesh?

No. An imported .glb is a scene, not a Mesh resource, so it cannot be assigned to the mesh property. Instantiate the .glb as a child scene under your node instead.

When should I not use AI vehicle generation?

Skip it for distant parked scenery where a simple prop model suffices, for modular customizable vehicles where a parts kit fits better, and for articulated mechs that need rigged joints, which should go through character-model with a rig pass instead.
