The following steps describe the recommended scarf creation pipeline for WANNA VTO.

1. Clo3D Scarf Creation

Setup

• Download the A-POSE_Scarves_avatar.zip and import into Clo3D (or compatible garment software).

• The avatar is positioned at world origin. If the scarf is longer than the ground plane, either raise the avatar or disable ground collision:
  • Right-click background → Simulation Properties → disable Ground Collision

• Set the avatar Skin Offset to 1 or 0.

Garment Modelling

• Model the scarf in thin visualisation mode (Textured or Monochrome surface).
  • A scarf should be exported from Clo3D as thin, so to have a proper visualisation you need to choose thin visualisation - Textured or Monochrome surface - in Clo3D.

• Add spacing for thickness:
  • Set Add’l Thickness – Collision (mm) for all parts (same value will be applied later in Blender).

• Recommended Particle Distance: 5 (smooth surface).
• In case of visible avatar mesh artefacts: 
  • Select the avatar → enable Divide Mesh → Resimulate.

• To improve folds, use Internal Lines.

• Change mesh type for all pieces to Quad (Optimized).

UV Layout in Clo3D

• Roughly place UVs in 0–1 space; final optimization will be done in Blender.
• If no thickness is applied or both sides share textures, UVs can be finalized here.

Export

• Export scarf as .obj 

2. Blender Adjustments

Setup

• Open Base_scarf_scene.blend
• Import scarf model and align to avatar.
• Do not move or scale the skeleton or avatar.

Thickness & Detailing

• Add thickness to the mesh (consistent with Clo3D settings).
• Clean topology and finalise details.

UV Mapping

• Create optimised UVs within the 0–1 coordinate range.
• Ensure minimum wasted space and relaxed UVs to prevent texture distortion.

Validation & Export

• Confirm that the model:
  • Is a single mesh with a single material
  • Has applied transformations (scale, rotation, location)
  • Origin aligns with world origin
• Export the model for texturing

3. Adobe Substance 3D Painter Texturing

Setup

• Use WANNA Shader + Scarves Environment Map.

Baking

• Bake details using the low-poly mesh as the high-poly source only if it has a clean, smooth, and detailed surface. 
• If the low-poly mesh lacks sufficient geometry for a smooth appearance, export a high-poly mesh from Clo3D and bake its details onto the low-poly mesh.
• Adjust AO map if needed.

Texture Creation

• Required maps: Base Color, Normal, ORM 
• Format: PNG, 2048×2048, 8-bit/channel.
• Import final textures to the Blender file.

4. Skinning & Export

Skinning

• Scarf must be a single mesh with a single material.
• Apply all transforms.
• Pivot points of scarf and skeleton must be at world origin.
• Use the skeleton from Base_scarf_scene.blend.
• Typically, only Pelvis and Spine bones should influence the scarf.
• Test deformation to ensure no unusual stretching or texture distortion.

Validation

• Check mesh deformation in different poses.
• Verify texture consistency (no stretching).
• Verify bone weights — zero influence from Hip, Collar, Shoulder, Neck, Head bones.

Final Export

• Select skeleton and scarf mesh.
• Export as .glTF + .bin + textures.

• Package in .zip ensuring size and texture limits are met.

5. WANNA Studio Upload

• Upload .zip to WANNA Studio.
• Select Male avatar gender for submission.
