Providing 3D Models

📁 File Format

Please deliver the model in one of the following formats:

• FBX
• OBJ
• GLB / GLTF

📏 Scale & Units

• Model the sofa at real-world size.
• For FBX, make sure the file's unit setting is correct when exporting — OV25 reads the FBX file's unit and scales the model to real-world size automatically.

🗺️ UV Mapping

• All models must be UV unwrapped within the default UV grid.
• Overlapping UVs are allowed.
• The UV layout should be mapped to a 3m × 3m area.

The alphabet/texture flow must run vertically, be centered within the sofa, and flow consistently around the arms.

🎯 Model Position

The model must be centered at coordinates: 0, 0.

🧭 Model Orientation

• All models must face forward.
• For corner or L-shaped sofas: always orient them right-hand facing to avoid lighting issues.

↔️ Normals

• All face normals must point outward (away from the mesh interior).
• Check for flipped normals before export; they cause invisible or black faces in the configurator.
• In your 3D app, use “recalculate normals” or “unify normals” so every face points the correct way.

Double-sided geometry (e.g. single-plane cushions) can look correct in the viewport but break in real-time rendering. Prefer proper outward-facing normals on solid geometry.

🏷️ Naming Convention (Meshes & Materials)

🛋️ Materials

• Assign a material to each part of the sofa.
• Most models will use:
  • Fabric – cushions, backs, arms, piping
  • Wood – legs (if wooden)
  • Metal – legs (if metal)

📐 Mesh Names

Rename each geometry part to match its corresponding component. Examples:

• Inside Back
• Outside Back
• Seat
• Legs
• Arms
• Cushions
• Piping
