Frequently Asked Questions

Create an account, upload a GLB or glTF file. Every upload generates a shareable turntable preview video automatically. You also get 10 preview renders to try custom settings before purchasing.

We accept GLB and glTF 3D model files. These are the standard formats used by most 3D modeling tools (Blender, Maya, 3ds Max, SketchUp, etc.) and e-commerce platforms (Shopify, Amazon, Google). You can also upload a ZIP file containing an OBJ model with its MTL and texture files (JPG/PNG) — ideal for 3D scanner exports from tools like Artec Studio, RealityCapture, and Metashape. The server converts to GLB automatically with optimized material settings.

Yes. Export your scan as OBJ with textures, zip the folder, and upload the ZIP file. DX.GL converts it to GLB automatically and sets material roughness to 1.0 for a realistic matte finish. The converted GLB is available for download from the model detail view — so even before rendering, you get a clean GLB with embedded textures and correct PBR settings. This works with exports from Artec Studio, RealityCapture, Agisoft Metashape, and similar photogrammetry or structured-light scanning tools.

Files up to 100 MB are supported. For ZIP uploads (3D scans), the limit applies to the ZIP file itself. Large files are uploaded in chunks automatically for reliability on slower connections.

No. DX.GL is entirely web-based. Upload, render, download, and share — all from your browser. There is also a RESTful API if you prefer programmatic access.

Standard renders are 1080p at 60 fps with H.264 encoding. 4K renders are 3840×2160 at 60 fps. Pro renders are 4K ProRes 4444 with an alpha channel for compositing. All tiers use GPU-accelerated 2× supersampling for anti-aliased edges.

Every render produces four assets: the full video (MP4 or ProRes .mov for Pro), a web-optimized MP4, a thumbnail video, and a full-resolution poster image. All assets can be downloaded individually or as a single zip bundle.

Most renders complete in minutes. The exact time depends on model complexity, chosen video length, and whether shadows or reflections are enabled. During busy periods, jobs may queue briefly before processing begins. A poster image is delivered first while the full video finishes encoding.

Yes. You can render the same model as many times as you like with different aspect ratios, backgrounds, durations, and effects. Credit cost depends on the quality tier — Standard costs 1, 4K costs 4, and Pro costs 16.

16:9 (landscape — for websites and product pages), 1:1 (square — for marketplaces and social media), and 9:16 (vertical — for Instagram Reels and TikTok).

Before each render you can choose: background color (solid hex or custom image), video length (3–15 seconds), starting rotation angle (−180° to 180°), forward/back tilt (−90° to 90°), ground shadows (on/off), reflective ground plane (on/off), and rotation easing (smooth ease-in/out or constant speed). Tilt is especially useful for showcasing shoes, bottles, and packaging from an angled perspective.

Yes. In the Create panel, switch from Color to Image mode. You can choose from system-provided gradients or upload your own branded background (PNG, JPEG, or WebP, up to 10 MB). The image is scaled to cover the output and cropped from the top-left, so logos in the corner stay anchored across all aspect ratios.

Yes. Click Preview Animation in the Create panel to open a real-time 3D turntable preview in your browser. The preview respects your current aspect ratio, rotation, and tilt settings so you can verify framing before spending a credit. It uses simplified matcap materials for speed, so lighting and textures will differ from the final render.

Batch rendering lets you select multiple models and render every combination of aspect ratio, background, and duration in a single operation. Variants that share the same model and render dimensions are processed from a single GPU pass for maximum efficiency.

Dataset renders produce calibrated multi-view training data instead of a video. Each dataset ZIP includes RGB images, depth maps (8-bit + 16-bit), normal maps, binary masks, a PLY point cloud, and nerfstudio-compatible camera poses (transforms.json). Three tiers are available: 100×800 (1 credit), 196×1024 (4 credits), and 400×2048 (16 credits). See Datasets for Research for details.

Shadows are baked using progressive light accumulation — thousands of randomized light positions produce natural soft-shadow contact detail. Shadow textures are cached per model so re-renders start instantly. The reflective ground plane adds a mirror-finish reflection with depth-based blur and distance fade for a studio look.

Five motion presets: Turntable (classic 360° loop), Hero Spin (fast spin that decelerates to the front), Showcase (gentle look-around), Zoom Orbit (360° with zoom), and Reveal (scale-up entrance with rotation). Each can be combined with custom length (3–15 s), starting angle, tilt, and easing.

No. We render your model exactly as uploaded — no geometry decimation, no texture compression, no LOD simplification. Textures up to 8K are rendered at full resolution on dedicated GPU hardware. This is a key difference from web-based 3D viewers, which typically strip detail to run in a browser.

Yes. Web-based 3D viewers depend on the end user’s GPU, browser, and operating system, so your product may look different on every device. Our pipeline renders on controlled hardware at fixed settings, producing an MP4 video that plays identically on every screen — desktop, mobile, tablet, any OS. No GPU compatibility issues, no missing features, no visual surprises.

No. DX.GL outputs standard H.264 MP4 videos that play natively in any browser, email client, or chat app. Recipients don’t need a GPU, 3D viewer, or any special software — just press play. This makes it easy to share 3D assets with product managers, executives, clients, and anyone else who doesn’t have a 3D workstation.

Credits are used to render videos. Standard renders cost 1 credit, 4K renders cost 4 credits, and Pro renders (ProRes 4444 with alpha) cost 16 credits. Each render includes a full video, web variant, thumbnail, and poster.

No. Credits stay on your account until you use them.

Every new account includes 3 free preview credits. Renders made with free credits include a subtle watermark and are limited to Standard quality. You can purchase credits to unlock the full version at any time — no need to re-render. The clean version replaces the preview at the same URL.

Payments are processed securely via Stripe. We accept all major credit and debit cards. EU businesses can enter a VAT ID at checkout to apply reverse charge.

Yes. Unused credits are eligible for a refund within 14 days of purchase. See our refund policy for full details.

Yes. If you need more than 100 credits, dedicated rendering capacity, API priority, or custom integrations, contact our sales team for a tailored quote.

Your model library supports grid, list, and export views with search, sort, and tag filtering. You can add titles, SKUs, and tags to any model for easy lookup.

Yes. Add up to 20 tags per model. Filter your library by one or more tags, or search by name, title, or SKU. Tags are also available via the API.

Files are deduplicated by content hash (SHA-256). If the same file is uploaded again, it links to the existing model instead of creating a duplicate — so you never waste storage or credits.

Yes. You can download the original GLB from any model’s detail view in the portal, or via the API.

Yes. Every rendered video gets a unique public URL that anyone can view — no account required. The share page includes play/pause controls, download buttons, and adapts to the video’s aspect ratio.

Yes. You can create gallery links that bundle multiple videos into a single shareable page. Useful for sending a full set of product variants to a client for review.

Paste one line of HTML: <video src="https://dx.gl/api/v/.../web.mp4" autoplay loop muted playsinline style="width:100%"></video>. Works on Shopify, WordPress, Squarespace, or any website. Every render includes a web-optimized MP4 built for fast loading. You can also copy the embed code directly from the video detail page.

Designers and 3D artists upload models and render videos. Everyone else — product managers, marketing, sales, external partners — reviews using standard video links or gallery pages. No installs, no GPU, no training. It bridges the gap between 3D authoring tools and the rest of your organization.

Yes. The RESTful API gives you full access to the rendering pipeline: upload models (file or URL), create renders, poll status, and download assets. Authentication uses Bearer tokens with scoped API keys.

Upload and manage models, trigger individual or batch renders, poll render status, download video and poster files, update titles/SKUs/tags, and check your credit balance. Full endpoint reference is available in the API documentation.

Interactive API documentation with examples, request/response schemas, and a quick-start guide is available at dx.gl/portal/docs.

Model files and rendered assets are stored on redundant cloud object storage. Your account data is stored in a managed PostgreSQL database. All data is encrypted in transit (TLS) and access is strictly per-user.

You can sign in with email and password, or use Google or Microsoft single sign-on (SSO). OAuth accounts are created instantly — no email verification step needed.

Yes. You can enable TOTP-based two-factor authentication from your account settings. Recovery codes are provided in case you lose access to your authenticator app.

Only you. All models, renders, and billing data are fully isolated per account. Shared video links are public by design, but only you can manage, delete, or re-render your content.
