Model Guidelines

You may use the reference models above (.blend, .fbx or .glb) as a baseline for asset modeling. These include both male and female base meshes (N1X and P4G3), along with example clothing assets. Geometry & Topology Requirements:
  • Assets must be game-ready, with optimized low-poly geometry.
  • Keep geometry clean and efficient - avoid unnecessary subdivisions or high vertex density.
  • All components of an asset must be joined into a single mesh/object. No loose parts or separate objects.
Materials & Textures:
  • Use a maximum of 3 materials per asset.
  • All textures must be 1024x1024px or smaller.
  • Do not use alpha transparency or opacity maps. Materials should be fully opaque.
Design Guidelines
  • Consistent Style: Maintain visual consistency
  • Appropriate Scale: Use realistic proportions
  • Clean Geometry: Avoid unnecessary complexity
  • Optimized Textures: Use efficient texture mapping
Animation Guidelines
  • Smooth Transitions: Create fluid animation sequences
  • Realistic Movement: Base animations on real-world physics if possible
  • Performance Focus: Optimize for web delivery

​

​
Animation Requirements
