Six steps, one take
Install the Blender addon
Download the free addon zip from GitHub Releases. In Blender, go to Edit → Preferences → Add-ons → Install and select the zip file.
Enable the addon
Search for “BlendMotion” in the addon list and check the box to enable it.
Check the Preflight Checklist
Open the BlendMotion panel in the 3D viewport sidebar (N key). The Preflight Checklist automatically verifies your IP address, active camera, port availability, and scene FPS.
Install the iPhone app
Download BlendMotion from the App Store.
Connect
Copy your IP address from the checklist (click the copy button), enter it in the iPhone app, and tap Connect.
Start & record
Click Start in the Blender panel. Move your iPhone to control the camera. Tap Record to capture keyframes on the timeline.
Good to know
Getting unstuck
Can’t connect?
Check the Preflight Checklist first — it flags most issues automatically. Ensure both devices are on the same Wi-Fi network and your firewall isn’t blocking the UDP port.
On iOS, also verify that BlendMotion has Local Network permission (Settings → Privacy & Security → Local Network), and disable any VPN that might route local traffic through a tunnel.
Laggy tracking?
Close other apps on your iPhone and reduce the distance to your Wi-Fi router for a stronger signal. Use a 5 GHz network if available.
Addon not showing up?
Make sure you’re running Blender 4.0 or later. Try restarting Blender after installation.
No active camera?
The Preflight Checklist will warn you if your scene has no camera. Add one with Shift+A → Camera and set it as active.
