The USDZ file works with iOS AR Quick Look, letting iPhone and iPad users view your models in their real-world space. Perfect for e-commerce, furniture visualization, and product try-before-you-buy experiences.
Can I edit materials and textures in the viewer?
Absolutely! Our real-time material editor lets you modify PBR materials directly in the browser. Select any mesh, then adjust color, roughness, metalness, and upload custom texture images. Changes appear instantly with physically-based rendering. All material edits are saved when you export to GLB or USDZ formats.
How do I add custom backgrounds to my 3D models?
Click the background picker in the viewer toolbar and choose "Upload Background Image" to use your own photos or textures. You can also select from preset solid colors. Custom backgrounds are saved with share links and exports (GLB/USDZ), ensuring consistent presentation. Great for product photography, brand matching, and professional presentations.
Can I convert 3D files in the browser?
Yes — client-side conversion/export to GLB, OBJ, STL, and PLY is available now (keeps files local). Use our 3D Converter or specific tools like OBJ to GLB converter. These client-side exports are available on Free and Basic plans. Server-side conversions for additional formats (e.g., STEP, FBX and others) are planned for future Pro features.
How secure are my 3D models?
Security is our top priority. All uploads are encrypted in transit and at rest. Models are only accessible via your unique share links. You control access—revoke sharing anytime. We never claim ownership of your intellectual property.
Can I embed 3D models on my website?
Yes! Pro and Enterprise plans include embeddable viewer functionality. Add interactive 3D models directly to your website, portfolio, or product pages with customizable branding and responsive design.
Do you offer customer support?
We provide comprehensive support through documentation, email assistance, and priority support for premium subscribers. Our team is here to help you make the most of 3D Model Studio.
Can I cancel my subscription anytime?
Yes, you can cancel or modify your subscription at any time with no penalties. Your models and data remain accessible, and you can export everything before cancellation.
Can I customize the appearance of my 3D models?
Absolutely! Choose from professional lighting presets (Studio, Bright, Soft) and customize background colors to match your brand. All settings are preserved when sharing, ensuring consistent presentation across all viewers.
What are the file size limits for uploads?
Free accounts can upload files up to 50 MB (covers most web-optimized GLB/GLTF and USDZ models). Basic accounts support up to 100 MB (complex models with detailed textures). Pro accounts support up to 200 MB (professional CAD and high-resolution game assets). Enterprise accounts have unlimited file sizes for industrial workflows. All files are optimized for fast web viewing while maintaining quality.
What are the benefits of sharing 3D files over the web?
Sharing 3D files online makes collaboration and feedback instant: recipients can view models without installing software, preview materials and lighting, embed models in websites or docs, and maintain access control and versions. Web sharing speeds review cycles and broadens reach for portfolios and product demos.
How do I optimize a 3D model for web viewing?
Reduce polygon count, bake and compress textures, use appropriately sized images (power-of-two when possible), and prefer compact formats like GLB for delivery. Remove unseen geometry, combine meshes when reasonable, and add LODs for complex scenes. Use our web readiness checker and GLB optimization check to analyze and improve performance across devices.
Can I 3D print models exported from 3D Model Studio?
Yes — you can export models for 3D printing. The most common formats for printing are STL (geometry only) and PLY (supports per-vertex color). Before printing, verify that your mesh is manifold, correctly scaled, and has no inverted normals. Use the 3D Print File Checker to validate your model, then run a quick repair and slicing step in a dedicated printing tool (e.g., Cura, PrusaSlicer) to check tolerances and supports.
Which file format should I use?
For web viewing and sharing, GLB is recommended (single-file, supports PBR materials and textures) — view them in our online GLB viewer. For 3D printing, use STL (widely supported) or PLY if you need per-vertex color. Use OBJ when you have separate texture files — you can convert OBJ to GLB for better web performance. Choose the format that best matches your workflow and downstream tools.
What are the limitations of client-side conversion (STL / PLY)?
Client-side exports to STL and PLY run entirely in your browser and keep files local, but they have limitations: large models may exceed browser memory or time out, advanced format conversions (e.g., CAD → STEP) are not supported, materials and textures may be lost (STL has no material support), and complex repairs are not performed. For very large or complex conversions, consider server-side workflows (planned for Pro).
What VR headsets are supported?
Our WebXR-based VR viewer works with all major VR headsets: Meta Quest 2, Quest 3, Quest Pro, HTC Vive, Valve Index, Windows Mixed Reality devices, and any headset with WebXR browser support. Simply open the viewer in your headset's browser (like Meta Quest Browser) and click the VR button. No app installation needed.
Can I use USDZ models in Android AR?
USDZ is an Apple-specific format optimized for iOS AR Quick Look. For Android AR, use GLB format with Google's Scene Viewer or model-viewer web component. Our platform exports both GLB (universal web/Android AR) and USDZ (iOS AR), so you can support AR experiences on all devices.
How do I optimize models for VR viewing?
For smooth VR performance: reduce polygon count (under 100K triangles for mobile VR), compress textures to 2K or lower, use fewer materials and draw calls, enable backface culling, and remove unnecessary meshes. Our viewer automatically adjusts rendering quality for VR mode, but starting with optimized models ensures the best experience across all headsets.
Why isn't the VR button showing in the viewer?
The VR button only appears when using a WebXR-compatible browser on a VR headset (e.g., Meta Quest Browser, Firefox Reality) or when a VR headset is connected to your desktop. To enable VR: 1) Use a VR headset's built-in browser, 2) Ensure WebXR is enabled in browser settings, 3) Grant permission for VR access when prompted, and 4) Connect your headset to your PC if using desktop browsers. Regular desktop/mobile browsers without VR hardware won't show the button.
Which file formats support custom background images?
Only GLB/GLTF and USDZ formats support background images because they are scene-based formats that can store environment properties. Other formats like OBJ, STL, and PLY are geometry-only formats that only describe the 3D mesh itself without scene-level data. When you export to OBJ/STL/PLY, the background won't be included—you'll need to reapply it in your target application. For workflows requiring backgrounds, always use GLB/GLTF (universal web) or USDZ (iOS AR).
