Two-lap circuit with first/third-person camera switch.
Two-lap circuit race against two rivals. Player car is a downloaded 3D vehicle on a normal racetrack. C/V switches first-person cockpit and third-person chase; the unattended demo shows both.
2.5D ring fight, skinned punch/kick, sun shadows off.
Best-of-three side-scroller on a 3D ring. Two skinned characters with walk, punch and flying-kick (jump) clips; W/S steps into the stage. Sun shadows off so the fighters stay readable.
Forest explorer: chest, Meshy knights, slash and light-arrow.
Third-person enchanted glade. A Black Eagle knight opens one supply chest
at the start (no weapon pickup), then fights Celestial Steel hostiles;
melee slash and a glowing light-arrow projectile. Bright daylight.
# 3D Object Generation Requirements — gameC_fighting_arena
## Overview
Generate game-ready 3D models for the fighting arena game. All character models
are generated from T-pose reference images using TRELLIS.2 or Hunyuan3D-2.1.
Weapon, prop, and architectural models are generated from reference images
using TRELLIS.2, TripoSG, or Meshy.
## Model Backend
- **Characters**: TRELLIS.2 / Hunyuan3D-2.1 (T-pose image → 3D model)
- **Weapons / Props**: TRELLIS.2 / TripoSG (ref image → 3D model)
- **Architecture**: Meshy image-to-3D (ref image → textured GLB)
## Quality Requirements
### Character Models (Warrior, Ninja)
- Triangle count: ≤100,000 tris
- PBR textures: 2048×2048
- T-pose orientation: arms along X-axis, feet on ground plane
- UV-mapped, game-ready, rigged-ready topology
- Realistic style matching Mortal Kombat visual reference
### Weapon / Prop Models
- Triangle count: ≤10,000–15,000 tris
- PBR textures: 2048×2048
- UV-mapped, game-ready
### Architectural Models
- Triangle count: ≤70,000 tris
- Embedded PBR textures with readable wood, stone, metal, and roof surfaces
- Preserve open interiors and continuous walkable floors
- Use meters for target scale; gameplay collision is authored separately in-engine
