Improve your Unreal Engine workflow with the TouchEngine Plugin for Unreal Engine

The TouchEngine Plugin for Unreal Engine allows you to load TouchDesigner Components into Unreal projects, process and manipulate them, and pass data back and forth all from within Unreal Engine. Users with Education, Commercial or Pro licenses can now use the new TouchEngine-UE plugin and unleash TouchDesigner power within Unreal Engine.

What does the plugin bring to the table?

The plugin is relying on the TouchEngine API, which is the same library that enables the Engine COMP within TouchDesigner. 

The plugin allows users to load TouchDesigner components saved as .tox files within Unreal Engine.

The TouchEngine process becomes a subprocess of Unreal and can pass CHOP, DAT or TOP data from Unreal to TouchDesigner, or retrieve CHOP, DAT or TOP data from the loaded TouchEngine component to be used in Unreal blueprints. Additionally, all custom parameters on the top level of the .tox component can be adjusted in Unreal’s interface or accessed in blueprints. 

What does it mean for TouchDesigner users?

TouchDesigner users can follow a workflow they are familiar with - you develop your custom components within TouchDesigner and set them up similarly to what you would do when setting up your components in a “black box” setup with the Engine COMP. 

All the features you are familiar with are here, whether it is using CHOPs data processing, writing custom GLSL shaders to drive particle systems or connecting to hardware with TouchDesigner’s extensive list of supported devices.

Anything you can use in the Engine COMP can now be used in Unreal through TouchEngine, input and output devices, protocols and external tools that TouchDesigner supports, Palette components, and TouchDesigner’s Python environment are all at your fingertips.

What does it mean for Unreal Engine users?

TouchDesigner is well known for stable, reliable custom software and fast prototyping. 

TouchDesigner becomes an extra tool in your Unreal toolbox that can speed up part of your development process, reducing production time and cost. Use TouchEngine to solve technical hurdles, connect to the world around you, add features that could be missing from Unreal, are difficult to implement or time consuming.

You get access to our data flow and signal processing with CHOPs and DATs, while also opening the door of a full compositing suite with our GPU TOPs and access to the Python world with our full featured Python API.

Furthermore, Unreal projects can now can access the hundreds of input and output devices that TouchDesigner supports boosting the interoperability of Unreal projects realized with the TouchEngine plugin.

Where to get started ?

All the essential links to get started are in our documentation.
