We are very happy to release Lightact v3.1.3 which includes TUIO support, better audio visualization capabilities (both on Lightact and on UE4 side) and a bunch of usability improvements and fixes.
But let’s go one step at a time.
TUIO is an open protocol that’s used for multi-touch interfaces. Lightact now supports it and you can use the data either to control Lightact itself or to pass it to Unreal Engine for advanced interactive VFX.
The interface to TUIO is very similar to all the other messaging readers. You simply insert a TUIO Reader node in the Devices window and associate it with a TUIO Listener node in the Layouts.
Audio Visualisation with Unreal Engine and Lightact | LightactThis video shows an example of using Lightact and Unreal Engine to create audio reactive visualizations.
Lightact analyzes audio using real-time Fast Fourier Transform (FFT) and sending the data to UE, which then uses this to create the visuals.
These are then sent back to Lightact for display. Everything is happening at around 60 frames per second.
Lightact v3.1.3 significantly expands the number of nodes that can be used for audio visualization – whether you are doing it in Unreal Engine as shown above,
or inside Lightact. As always with Lightact, there are hundreds of different possibilities.
We’ve also added a number of usability improvements that will help you get to where you want to be faster and easier.
You can set individual Art-Net channels using Art-Net Channel Setter nodes.
On top of that, every Art-Net node in the Devices window now gives you the power to set universe-wide overrides, such as All Full or All Zero, for example. This allows for easier on-site debugging of DMX patching.
