Notch Builder

The Real-Time Authoring Tool


An Artist’s Tool

We’ve built an authoring tool that not only brings the incredible freedom of real-time, but is also astonishingly flexible. It’s useful whether you scratch the surface or explore its outer limits.

Intuitive UX

The UI is designed to be familiar and intuitive to use, based on our decades of experience with 3D and compositing software. Notch takes industry standard paradigms and finely tunes them for a real-­time workflow.


Notch Builder works in real-time, which means you get to make chances and see them take effect as you work. You can also render to video using our powerful ray-tracing and path tracing features.


Fully featured

Powerful Nodes

Our interface is based on nodes: small, simple building blocks, connected together logically and intuitively to make spectacular creations. The only limitation is your imagination.

Set Your Timeline

From the Keyframe-Based Curve Editor to the NLE layout, Notch provides the tools to realise your visual narrative. And if you need to use the sequencer of a 3rd party tool (media server / lighting desk / sensing software), simply expose the desired node parameters.

Dynamic Lighting & Materials

Notch’s physically based material system gives you all the tools you would expect; normal, displacement, specular and roughness maps. Standard light types, shadows and image based lighting.

But Notch takes you beyond the expected, to voxel cone tracing for ambient occlusion and global illumination, mix in reflection & refraction support and you’ve got something special.


Bringing extraordinary interactivity without months of coding


Notch Playback supports both depth and RGB feeds from Kinect v1 and v2, whether embedded in a media server or standalone.

OSC / Midi / ArtNet

Notch Playback supports input from OSC, ArtNet and Midi for making dynamic and responsive scenes.

Scripting Engine

Need the extra layer of logic, Notch comes with a Javascript engine for manipulating scenes in real-time.

Tracking Effects

With Notch’s visual effects engine you can track moving performers on stage, including wispy smoke, rivers of water or fire. A great partner to Blacktrax™.

Audio Reactive

Equipped with FFT analysis, Notch can make your scenes respond to the live audio feeds.


One tool – multiple canvases

Notch is being used globally to deliver real-time content in every possible setting, from the bespoke fixed install, to the summer festival tour. With the optional Notch Playback license, you can take your content created in Notch Builder to industry-standard media servers and stand-alone applications.

Particles, Cloners, Grading, The Works

A powerful and sophisticated real-time visual effects engine in your hands

Particles from video and geometry

Notch has been crafted to fully integrate between particles, fields, geometry and textures. Seed your particles from a live video source or textured geometry. Then use the particles to generate elements like geometry, light sources and more.

Millions of particles in real-time

Sophisticated particle effects require huge numbers of particles. Notch’s real-time GPU based solver is immensely powerful, processing millions of particles every frame through a great range of affectors.

Cloners – for simple complexity

Clone 3D objects in grids, radially, or with iterative transform functions. Clone to mesh vertex or polygon positions or image pixels or particles or voxels and more. Then animate it all with an array of affectors.

Fields & Fluids

Incredible fluidity, in 2D and in 3D. Notch provides a phenomenal array of processing tools; SPH & FLIP fluid simulations, optical flow, feature tracking and mesh generation.

Volumetrics & Voxels

Voxels and volumetrics have been made a mainstay of the engine, being created from meshes, particles, fields or even Kinect data. Notch delivers stunning shaded real-time volumetric renders and simulations.

All features work together seamlessly in an integrated 3D workspace


A Complete Tool

Whether you are using Notch for part of your workflow or all of it, we’ve provided an extensive tool, including compositing, grading and strong inter-operability with other packages.

Audio Reactive

Control visuals with audio. Drive any attribute with spectrum analysis data from audio files or live feeds to make effects audio reactive instantly.

Compositing & Grading

Notch Builder has a full suite of compositing and grading tools. LUTs, levels, thresholds, HSV colour keying, blend modes, it’s all there.

Import / Export

Import / export from many other industry-standard packages, e.g. Cinema4D, 3DS Max, Maya, Lightwave, Blender, RealFlow. Notch works with you.

Network Editing

With Notch Builder Pro you can remotely edit scenes over a network while they are running live on media server. This ability to tweak and author your work on final canvas gives unparalleled levels of creative freedom.
