Why we like it

Plastiq's first shipped add-on, TunnelBeat earns a place in the superhive library for turning a single BPM value into a ready-to-render looping tunnel with its camera and drivers already set up.

What is Tunnelbeat?

TunnelBeat is an add-on for Blender that generates a BPM-synced infinite tunnel animation. Enter a BPM value, confirm, and Blender builds the tunnel, places a camera, and sets up a driver-based rotation that locks the animation cycle to your tempo, with no keyframing and no math required. The add-on runs from a single operator, triggered with Shift + T in the 3D viewport.

The rotation speed is derived directly from your BPM, so the tunnel segments scroll at exactly the rate the beat implies. The result is a near-seamless loop that holds up at any length, and from there you can edit lighting, camera position, and materials. Controls cover scroll speed, gridline thickness and density, a Grid or Mesh mode, loop length, and an option to clear the scene before generating.

TunnelBeat is good for music visualizers, VJ loops, motion graphics backgrounds, and anything that needs a render-ready tunnel without building one from scratch. Loop seams are near-seamless rather than mathematically perfect; at 60fps the difference is sub-frame and not visible in motion. It works best in a new, clean scene and requires Blender 5.0 or later.

Who is Tunnelbeat best for?

Tunnelbeat is best for music visualizers, VJ loops, and motion graphics backgrounds that need a render-ready tunnel without building it from scratch.

How much does Tunnelbeat cost?

Key features

  • Driver-based rotation that locks the animation cycle to your BPM, with no keyframing
  • BPM input that any tempo syncs to
  • Speed setting for slow, medium, or fast scroll relative to the beat
  • Gridline thickness (thin, normal, thick) and density (sparse, normal, dense) options
  • Mode control: Grid for a clean wireframe look or Mesh for a subdivided surface
  • Loop Length to multiply the base period for longer renders
  • Clear Scene option to wipe the scene before generating

Frequently asked questions

Does TunnelBeat work with Blender 5.0?

TunnelBeat runs on Blender 5.0 and later, with listed compatibility for Blender 5.0 to 5.1. The developer notes it has not been tested in earlier versions, so running it below 5.0 isn't supported. It's published as a Blender extension of the add-on type, licensed under GPL. If you're on a 5.x release, you can install it and trigger it directly in the 3D viewport. For versions outside that range, check the developer's page before relying on it in a project.

How do I run TunnelBeat in Blender?

TunnelBeat runs from a single operator inside Blender. Press Shift + T in the 3D viewport to initiate the add-on, enter your BPM, and confirm to generate the tunnel. Blender then builds the tunnel, places a camera, and sets up the driver-based rotation that locks the loop to your tempo. From there you can edit lighting, camera position, and materials to suit your shot. The add-on works best in a new, clean scene and includes an option to clear the scene before generating.

Are TunnelBeat's loops perfectly seamless?

TunnelBeat produces a near-seamless loop rather than a mathematically perfect one. The rotation speed is derived directly from your BPM, so the tunnel segments scroll at exactly the rate your beat implies, and the loop holds up at any length. According to the developer, the seam difference at 60fps is sub-frame and not visible in motion. If you need the cycle to run longer, the Loop Length control multiplies the base period for extended renders.

What visual styles does TunnelBeat's Mode control offer?

TunnelBeat offers two looks through its Mode control: Grid produces a clean wireframe, while Mesh produces a subdivided surface. Alongside mode, you can set scroll speed to slow, medium, or fast relative to the beat, adjust gridline thickness between thin, normal, and thick, and change gridline density from sparse to normal to dense. These options let you shape the tunnel's appearance, together with the lighting, camera position, and materials you can edit directly in the scene.

Is TunnelBeat free to use?

TunnelBeat is listed as free in this catalog. It's distributed as a Blender add-on under a GPL license, so you're free to use it under those terms. Since licensing and availability can change over time, check the developer's page for the current details before you download. The add-on covers the full setup from a single operator, so once installed there's nothing extra to configure beyond entering your BPM and adjusting the exposed controls.
