This document outlines the category-specific requirements for scarf models used in WANNA Virtual Try-On (VTO).
All General 3D Model Requirements apply to scarves.
If your scarf model is intended for 3D Viewer, refer instead to 3D Viewer Model Requirements, as 3D Viewer has unified requirements regardless of product category.
Main Requirements
| Requirement | Details |
|---|---|
| Max triangles per scene | 130,000 (recommended: ~60,000) |
| Max primitives per scene | 105 (but single mesh only; multiple meshes not supported) |
| Max texture size | 2048x2048 |
| Total texture pixels per model | 18,873,368 px |
| Archive file size (geometry + textures) | ≤ 50 MB (recommended: <15 MB) |
| Model scale | True-to-size (1:1) |
| File format | glTF (.gltf) or GLB (.glb) only |
| Skeleton | Must match bone count and hierarchy in Base_scarf_scene.blend; only one correct skeleton allowed |
| Geometry | Must have clean topology, especially in folds; scarf should have visible thickness where edges are exposed |
| Materials | Backface culling disabled; use WANNA Shader + WANNA Environment Map for realism |
Modelling Recommendations
- Fit the scarf closely to the provided avatar in A-pose — no gaps and no intersections with the body.
- Use consistent thickness where visible; add thickness in Blender if not done in Clo3D.
- Keep spare UV space to a minimum; relax UVs to reduce distortion.
- Bake small details from a high-poly mesh into textures to reduce poly count while preserving visual quality.
- Use normal maps instead of geometry for very fine details to avoid aliasing and keep polygon count low.
- If your scarf design includes gems, refer to How to add beautiful gems to 3D models for detailed instructions on creating high-quality gem elements.
