How to export Position/Rotation/Scale Animations from 3ds Max to GLB (USDZ Compatible)

Exporting simple transform animations (position, rotation, scale) - no bones, no skin, no morphs.

Step 1: Animate using keyframes

(Skip this if your objects are already animated)

1. Select the object (e.g., drawer, box, part)
2. Enable Auto Key
3. Set keyframes on Position / Rotation / Scale at different frames
4. Play the timeline to preview
5. Important: Each animated object must be a separate mesh

Step 2: Open Babylon Exporter

Go to:

Rendering > Babylon File Exporter

Choose export format:

GLB (.glb) - best for USDZ conversion

Step 3: Export settings

In the Babylon Exporter window:

• Export animations → checked
• Auto bake animations → checked
• Export only selected → optional
• Do not use bones or skin for this method

🎯 Keep all animated objects selected before export if using "Export only selected".

Step 4: Export

• Click Export and save as .glb
• Wait for the export process to complete (check log if needed)

Notes:

• Animations must be on transform tracks (no modifiers or vertex animation)
• Works great for mechanical or modular motions (drawers, doors, panels)
• USDZ does not support vertex-level animation or morphs via this pipeline
• Exporting Bone-Based Animations from 3ds Max to GLB (for USDZ)
