3D Modeler: Preparing Furniture for AR (Android and iOS)

Text:

We are looking for a specialist to prepare 3D models of upholstered furniture for the AR catalog. I will provide the source models and fabric textures.

Tasks:

1. Texturing the finished models (sofas, chairs) with our materials.
2. Optimizing the mesh for mobile devices (up to 25 MB).
3. Exporting in two formats: .glb (for Android) and .usdz (for iOS).

Requirements:

• Experience in creating/converting models specifically for mobile augmented reality.
• Understanding the difference in material rendering in ARCore and ARKit.
• Ability to maintain the photorealism of the fabric at a low file weight.

In your response, please indicate: the cost for a pair of files (GLB + USDZ) for one model and examples of your work that can be launched in AR.

2. Technical Assignment (TA)

Input Data:

• 3D source, texture pack, fabric tiling size.

Requirements for the Result:

1. Formats: For each model, 2 files are needed:
   • GLB (binary glTF) — for Android/Web.
   • USDZ — for iPhone/iPad.
2. Weight Limit: Total no more than 25 MB for each file.
3. Optimization:
   • Polygon count: up to 150k triangles (preferably less).
   • Textures: 2K, PBR format (Roughness/Metalness workflow).
4. AR Specifics:
   • Scale: Scale strictly 1:1 (in meters or centimeters), so that in reality the sofa does not end up the size of a house or a matchbox.
   • Pivot Point: The pivot point must be strictly at the center of the base (at the bottom), so that the model "sticks" to the floor correctly.
   • Materials: The fabric in USDZ should look the same as in GLB (sometimes separate adjustments for brightness/mattness are required for Apple devices).
