How can Webflow users incorporate 3D objects and animations into their websites, interact with them using interactions, scrolling, and mouse movement, and import models and animations from Blender?

To incorporate 3D objects and animations into Webflow websites and create interactions using scrolling, mouse movement, and interactions, users must utilize external tools in combination with Webflow’s native capabilities.

​

1. Create the 3D Model and Animation in Blender

​

• Design and animate your 3D object in Blender using keyframes, materials, and mesh optimizations.
• Export the model in .glb (recommended) or .gltf format for web use. These formats are compatible with most JavaScript 3D renderers like Three.js or Spline.

​

2. Choose a Hosting or Embedding Method

​

• You cannot upload or render 3D models directly in native Webflow elements.
• Use one of the following options:
• Spline: A no-code-friendly 3D design tool that exports embeddable iframes.
• Three.js or model-viewer: Use custom code embeds in Webflow to integrate 3D viewers directly.
• Sketchfab: Upload your model and embed it using an embed URL.
• For interactive, low-code embedding, Spline is often the easiest for Webflow users.

​

3. Embed the 3D Model in Webflow

​

• Drag an Embed element into your Webflow canvas where the 3D object should appear.
• Paste the iframe embed code from your chosen tool (e.g., Spline or Sketchfab).
• Use loading="lazy" in the iframe for performance optimization, and modify styling using Webflow classes.

​

4. Add Interactions (Mouse, Scroll, etc.)

​

• Use Webflow Interactions panel to set triggers like:
• While scrolling in view
• Mouse move over element
• Page load or click
• To apply interactions:
• Wrap your embed or 3D container in a div block.
• Set interaction triggers on that container (e.g., mouse movement can affect embedded 3D object opacity or position).
• For Scroll-based effects, animate the container’s opacity, position, scale, or apply transforms.

​

5. Create Custom Interactivity (Optional, with Code)

​

• If you need dynamic interaction with the 3D object (e.g., rotating with cursor), use custom JavaScript.
• Three.js or model-viewer lets you respond to scroll and mouse inputs:
• Add your code in Page Settings > Custom Code header/footer or using an Embed element inside the canvas.
• Use GSAP or Locomotive Scroll in tandem with 3D libraries for synced animation with scroll.

​

Summary

​

To add and control 3D objects and animations in Webflow, build them in Blender and export to .glb or .gltf, then embed with tools like Spline or Three.js. Use Webflow’s interactions panel to trigger animations with scroll or mouse activity. For advanced interactivity, embed custom JavaScript to manipulate 3D behavior within the Webflow environment.
