When saving USDZ 3D models, focus on optimizing geometry, compressing textures, and using USDZ-compatible tools to balance file size, quality, and compatibility.
Optimize geometry by reducing unnecessary polygons (e.g., decimation) to keep files lean. Compress textures with JPEG (photos) or PNG (transparency) and avoid embedding large files. Use tools like Blender (with USD add-ons), Maya, or Reality Composer—they support native USDZ export without losing format features.
Useful for AR apps (e.g., Apple ARKit) where fast loading matters, or e-commerce product previews where iOS compatibility is key.
If you’re new, start with a simple model (like a textured cube) in Blender—test how optimizations affect file size and quality before working on complex projects.
