3D Nodes

3D nodes bring a new dimension to your creative workflows. They use AI to transform photos, sketches, or text descriptions into fully-textured 3D models ready for games, e-commerce, and 3D printing.

What Are 3D Nodes?

3D nodes generate 3D models using AI. They can:

• 🖼️ Image to 3D — Convert photos into 3D models
• ✏️ Sketch to 3D — Transform line art into textured models
• 💬 Text to 3D — Generate 3D models from text descriptions
• 🎮 Interactive preview — View and manipulate 3D models directly in the canvas

Adding a 3D Node

1. Open the node sidebar on the left
2. Find 3D in the list
3. Drag it onto your canvas

3D Node Inputs

3D nodes accept different inputs depending on the generation mode:

Generation Modes

Image to 3D

Transform photos into 3D models:

[Upload Node] → [3D Node (Image to 3D)]
Your photo → Interactive 3D model

Best for:

• Product photography
• Object scanning
• E-commerce 3D views
• Game asset creation

Pro tip: Provide multiple views (front, back, left, right) for better 3D reconstruction accuracy.

Sketch to 3D

Convert line art or sketches into textured 3D models:

[Upload Node] → [3D Node (Sketch to 3D)]
Your sketch → Textured 3D model

Best for:

• Concept art to 3D
• Character design prototyping
• Quick 3D mockups from drawings

Note: Sketch mode requires a prompt to describe colors and materials since sketches are typically black and white.

Text to 3D

Generate 3D models directly from text descriptions:

[Text Node] → [3D Node (Text to 3D)]
Your description → Generated 3D model

Best for:

• Quick 3D concept generation
• Prototyping objects
• Creating 3D assets from ideas

3D Node Settings

Model Selection

Generation Mode

Choose how you want to generate your 3D model:

Enable PBR Materials

Toggle to generate Physically Based Rendering materials:

• Off — Standard textures
• On — PBR materials for realistic lighting in 3D engines

When to use: Enable for game engines (Unity, Unreal) or professional 3D software.

Face Count

Control the polygon complexity:

Default: 500,000 (balanced quality and performance)

Generation Type

Choose the output style:

Viewing 3D Models

When generation completes:

1. Interactive preview appears in the node
2. Drag to rotate the model
3. Scroll to zoom in/out
4. Shift+Drag to pan
5. Fullscreen button to view larger
6. Download button to save as GLB file

Controls

Output Format

3D nodes output models in GLB format:

• Industry-standard format
• Includes geometry, textures, and materials
• Compatible with:
  • Unity
  • Unreal Engine
  • Blender
  • Three.js
  • Most 3D software

Multi-View Image-to-3D

For best results with Image-to-3D, provide multiple views:

[Upload Node (Front)] ─┬→ [3D Node]
[Upload Node (Back)]  ─┤
[Upload Node (Left)]  ─┤
[Upload Node (Right)] ─┘

Tips for Multi-View

• Use consistent lighting across all views
• Keep the object centered in each image
• Use the same distance/zoom level
• Ensure backgrounds are clean or similar

Workflow Examples

Product 3D Model

1. Add Upload Node with product photo
2. Add 3D Node with Image-to-3D mode
3. Connect Upload → 3D (Front Image)
4. Optionally add back/side views
5. Enable PBR Materials for realistic rendering
6. Run to generate 3D model
7. Download GLB for your e-commerce platform

Character from Sketch

1. Add Upload Node with character sketch
2. Add Text Node with color/material description
3. Add 3D Node with Sketch-to-3D mode
4. Connect Upload → 3D (Front Image)
5. Connect Text → 3D (Prompt)
6. Run to generate character model

Quick Concept Object

1. Add Text Node with object description
2. Add 3D Node with Text-to-3D mode
3. Connect Text → 3D (Prompt)
4. Run to generate concept model

Tips for Better 3D Models

Image-to-3D Tips

• Use high-resolution, well-lit images
• Avoid extreme angles or occlusions
• Clean backgrounds improve results
• Multiple views dramatically improve accuracy

Sketch-to-3D Tips

• Use clear, clean line art
• Avoid excessive detail in sketches
• Write detailed prompts for colors and materials
• Example prompt: "Orange tabby cat with white paws, fluffy fur texture"

Text-to-3D Tips

• Be specific about shape and proportions
• Mention materials and textures
• Describe the object from multiple perspectives
• Example: "A rustic wooden treasure chest with iron bands, ornate lock, weathered dark oak finish"

Common Issues

Model Looks Flat

• Add side/back view images
• Increase face count
• Use cleaner input images

Textures Look Wrong

• Enable PBR materials for better lighting
• Use higher quality input images
• For sketches, write detailed material prompts

Download Issues

• GLB files are large — wait for full download
• Check browser download settings
• Try downloading in fullscreen gallery view
