Getting Started

Creating Your Account

To start using Rendertize, visit app.rendertize.com/signup and create an account with your email and password.

• Email verification — You'll receive a 6-digit code at your email. Enter this code on the confirmation page to verify your account.
• Password requirements — Your password must be at least 6 characters and include at least one uppercase letter, one lowercase letter, one digit, and one symbol (e.g., @, #, $, %).
• Starting credits — New accounts receive 100 free credits to get started, plus any plan-based monthly grants.

The Dashboard

After logging in, you'll see your dashboard with three main sections:

• Credit Balance — Your remaining credits appear in the top-right corner. Credits are consumed by API renders and AI metadata generation; browser screenshots are free.
• Render Workspace — Click "New Render" to start the core workflow: upload a 3D model, configure settings, and render.
• Listing History — View all previously saved listings, search by name, and re-copy metadata.

Understanding the Free Tier

Rendertize offers lifetime access to a Free tier:

• Credits — 20 lifetime credits (one-time, do not refresh)
• Model size — Max 50 MB per upload
• Render resolution — Up to 1024x1024 pixels
• Storage — 1 GB total

For higher limits and faster monthly credit grants, see our pricing page for Starter and Pro plans.

The Rendering Workflow

Step 1: Upload Your 3D Model

Click "New Render" from your dashboard. You'll see an upload area where you can drag-and-drop or select a file.

• Supported formats — GLB and glTF files only. (Tip: Export your 3D model from Blender, Maya, or similar tools as GLB for best results.)
• File size — Check your plan's limit (Free: 50 MB, Starter: 100 MB, Pro: 100 MB).
• Model load time — The model will load in the 3D viewer within 10 seconds.
• Your model is safe — GLB files are loaded and rendered entirely in your browser. They are never uploaded to our servers.

Step 2: Preview & Configure

Once your model loads, the interactive 3D viewer appears on the left with 10 control panels on the right:

Camera Controls

• Yaw — Rotate the model left/right around the vertical axis.
• Pitch — Rotate the model up/down around the horizontal axis.
• Distance — Zoom in/out on the model (closer = larger on screen).

Model Rotation & Scale

• Rotation X/Y/Z — Rotate the model around its own axes (independent of camera).
• Scale — Enlarge or shrink the model uniformly.

Lighting

• Intensity — Brightness of the light source (0–100%).
• Shadow Softness — Softer shadows look more natural; harder shadows look more dramatic.
• Angle — Direction of the light (0–360°).
• Exposure & Tone Mapping — Fine-tune the final image brightness and contrast.

Environment & Skybox

• Environment — Background lighting that affects the model's appearance. Options: Neutral, Legacy, Solid Color, Gradient, HDR file, or URL.
• Skybox — Visual background behind the model. Options: None, Solid Color, Gradient, Image file, or URL.

View Mode

• Normal — Full color and texture rendering.
• Clay — Renders the model in a neutral clay color, useful for evaluating geometry without distracting textures.
• Wireframe — Shows the model's edge structure overlaid on geometry.
• Wireframe + Material — Combines wireframe edges with texture/color.

Background & Resolution

• Background — What appears behind the model. Options: Transparent, solid color, gradient, image, or URL.
• Resolution — Output size in pixels (e.g., 1024x1024). Higher resolutions cost more credits on API renders.

Step 3: Browser Render (Free)

Click "Render & Download" to capture a screenshot of your current model view at the selected resolution. This is free and downloads instantly to your computer (usually within 3 seconds).

• No credits consumed.
• Perfect for quick previews or social media.
• Quality depends on your browser's WebGL capabilities.

Step 4: API Render (High-Quality, Paid)

Click "Render & Compare" to generate a high-quality render on our servers and compare it side-by-side with your browser version.

• Credit cost — 1 credit for up to 1024px, 2 credits for up to 2048px, 4 credits for up to 4096px.
• Processing time — Usually 10–30 seconds; you'll see the API render appear in the comparison modal once ready.
• Quality — API renders use professional rendering engines and often produce smoother, more polished results than browser screenshots.
• Error handling — If the render fails or times out, no credits are deducted and you'll see an error message. You can retry immediately.

The Comparison Modal

When you click "Render & Compare," a modal opens showing:

• Browser render (left) — Your free screenshot.
• API render (right) — The high-quality paid version.
• Download buttons — Each render can be downloaded individually.
• Camera info overlay — Shows the exact camera settings used for each render.

This lets you decide which render quality is right for your listing before committing to multiple renders.

AI Metadata Generation

What is Metadata?

When listing a 3D asset on marketplaces like CGTrader, TurboSquid, or Fab.com, you need:

• Title — A short, descriptive name (e.g., "Low-poly Forest Tree").
• Description — A detailed explanation of what the asset is, its features, and use cases (200–500 words).
• Tags — Keywords that help buyers find your asset (10–20 per marketplace).

Creating compelling metadata for each marketplace (and each asset) is time-consuming. Rendertize automates this using AI.

How It Works

To generate metadata:

1. In the render workspace, click "Generate Metadata" after rendering.
2. Select the rendered image(s) and target marketplaces (CGTrader, TurboSquid, Fab.com).
3. Optionally, enter custom instructions (e.g., "This is a medieval weapon" or "Emphasize PBR-ready materials") to guide the AI.
4. Click "Generate" — the AI analyzes your render and model geometry, then produces marketplace-optimized metadata in 10–15 seconds.

Credit Cost

10 credits per metadata generation (regardless of marketplace count). If you generate metadata for 1 asset and 5 marketplaces, that's 1 generation = 10 credits.

Editing Generated Metadata

Generated metadata is a starting point. You can edit any field (title, description, tags) directly in the interface before copying. Your edits persist for the current session.

Copying Metadata

Once generated (and optionally edited), you can:

• Click the copy button next to any field to copy that text to your clipboard.
• Click "Copy All as JSON" to copy the entire metadata structure for all selected marketplaces at once.
• Paste the JSON into a spreadsheet or directly into marketplace publishing tools.

What the AI Can Do

• Analyze your render — The AI examines your 3D model's geometry, materials, and visual appearance.
• Generate marketplace-specific metadata — Each marketplace has different conventions. The AI tailors titles, descriptions, and tags to match each platform's style and buyer expectations.
• Honor your custom instructions — If you provide guidance (e.g., "this is a sci-fi prop" or "optimize for game engines"), the AI incorporates that into the output.

Limitations & Tips

• Review before publishing — AI-generated metadata is a draft. Always review for accuracy and relevance before publishing on a marketplace.
• Your 3D files are private — Only temporary analysis images are sent to our AI provider; your original GLB files are never uploaded.
• Regenerate if needed — If you don't like the output, adjust your custom instructions and regenerate (costs another 10 credits).

Saving & Managing Listings

Saving a Listing

After generating metadata, click "Save Listing" to store all your work (renders, metadata, settings) for future reference.

• What gets saved — Asset name, selected renders, generated metadata for each marketplace, creation timestamp.
• What doesn't get saved — Render parameters (camera, lighting, etc.) are not persisted. Metadata is saved as-is at the moment of saving.

Viewing Your History

Click "Listing History" from the dashboard to see all saved listings. Each card shows:

• Asset name — What you called it.
• Thumbnail image — A preview of the primary render.
• Marketplace badges — Which marketplaces this listing targets.
• Timestamp — When it was created.

Searching & Filtering

Type in the search box to filter listings by name. You can also navigate through pages if you have many listings.

Re-using Metadata

Click on any listing card to open it and view the metadata again. You can:

• Copy individual fields or the entire JSON to your clipboard.
• Use the metadata for re-listing the same asset on additional marketplaces.
• Reference it while creating manual listings elsewhere.

Deleting a Listing

Click the delete button on any listing card to remove it from your history. This action is permanent and cannot be undone.

• Deleted listings are removed from your dashboard.
• Renders are also deleted from storage.
• No credits are refunded for deleted listings.

Important Notes

• Listings are read-only — You cannot edit a saved listing's metadata. If you need different metadata, start a new render and generate fresh metadata.
• Renders are tied to listings — Each listing saves the renders selected during metadata generation. If you delete a listing, its renders are also deleted.

Understanding Credits & Billing

What Are Credits?

Credits are the currency used to purchase API renders and AI metadata generation. Browser screenshots are free.

Credit Cost Breakdown

• Browser render (screenshot) — 0 credits (free).
