THIS ADD-ON RUNS ON BLENDER 5+ AND HAS NOT BEEN TESTED IN EARLIER VERSIONS

TunnelBeat generates a BPM-synced infinite tunnel animation in seconds. Enter your BPM, hit OK, and Blender builds the tunnel, places A camera, and sets up a driver-based rotation that locks the animation cycle to your tempo — no keyframing, no math.

How it works

The rotation speed is derived directly from your BPM, so the tunnel segments scroll at exactly the rate your beat implies. The result is a near-seamless loop that holds up at any length. From there, the artist can edit lighting, camera position, and materials.

Press hotkey Shift + T to initiate the add-on.

 Controls

• BPM — enter any tempo and the animation syncs to it
• Speed — slow, medium, or fast scroll relative to the beat
• Gridline Thickness — thin, normal, or thick wireframe lines
• Gridline Density — sparse, normal, or dense segment count
• Mode — Grid for a clean wireframe look, Mesh for a subdivided surface
• Loop Length — multiply the base period for longer renders
• Clear Scene — optionally wipe the scene before generating

Good for

Music visualizers, VJ loops, motion graphics backgrounds, and anything that needs a render-ready tunnel without building it from scratch.

Notes

Loop seams are near-seamless but not mathematically perfect — at 60fps the difference is sub-frame and not visible in motion.

The modifier works best in a new, clean scene.

Blender 5.0+. Single operator,  Press Shift+T in the 3D viewport.

This is the first add-on I've shipped. I hope to add more features in the future.
