Released 20. November 2018.

  • BugSplat: we’ve included a crash report feature which should, in the event of a crash, create a pop-up window through which you can report the details of the crash and your contact details so we can reach out if we need more information.
  • Code signing: we’ve included a code signing certificate, so you shouldn’t be getting that annoying Unknown publisher warning when you install Lightact.
eDMX (Art-Net) Fixtures
  • Much improved Fixture placement rendering: Fixture placement rendering has been re-built from the ground up and its efficiency increased by an order of magnitude. Now you can easily render tens of thousands of pixels with no significant FPS drop.
  • Fixture placement with obj: You can create a Fixture placement with obj file where you can filter the objects in the file according their attributes such as vertices number, coplanarity and surface area. You can also automatically rotate the fixtures as per the rotations of the objects in the file.
  • Fixture placement with csv: You can create a Fixture placement with a csv file where in the csv file you insert locations, rotations, fixture type and DMX address and Lightact will create a Fixture placement based on this data.
  • 1st pixel red: This functionality colors the first pixel of the fixture in red. This allows you to inspect the orientation of the fixtures in the Fixture placement.
  • GUI improvements: we’ve added a number of gui and ease-of-use improvements such as display of last DMX channel of a fixture in the Visualizer, better fixture dimension setting in Fixture editor window and so on.
Layer Layouts
  • Find contours node finds and outputs OpenCV contours from an incoming cvMat input.
  • Find circles node finds and outputs minimum enclosing circle from an incoming cvMat input.
  • Shared memory sender node has been upgraded so that you can pass Contours to Unreal Engine.
  • Set texture channel node allows you to override one or several channels of an incoming Texture with a set value.
  • Video reader node has been fixed so that it doesn’t show the last frame upon entering 2nd and above loop.
  • Node descriptions now appear on a tooltip when you hover above the node.
  • IP cameras are now easier to set up.


Released 23. September 2018.

  • Watermarks: in Free license, all video outputs are watermarked. This includes physical video outputs, Spout and NDI.
  • Visualizer gizmos have been added. Now it is possible to move rotate and scale objects in the visualizer with the gizmos.
Layer Layouts
  • Custom Shader node allows you to write custom GLSL programs and use them in Lightact.
  • Write texture to file node writes a Lightact texture into a jpg file on the disk.
  • Write string to file node writes a Lightact string to a txt file on the disk.
  • Read string from file node reads a text file and converts it into a string.
  • Sunset and sunrise node has been introduced. Based on latitude, longitude and UTC offset it calculates local sunset and sunrise times.


Released 7. September 2018.

Projection mapping
  • Content source of a projector can be assigned directly to a Canvas in the same way as for the video screens.
  • Canvas setup window has been completely reworked. Now you can warp, softedge and color correct the content directly from this window.
Layer Layouts
  • Video reader, Hap video reader and Image reader nodes have a new Filepath string input. This allows playback of videos and images without having to import them as an asset.
  • Filepaths from folder node has been introduced. It outputs an array of strings of all files in a folder. Subfolder search and filtering by file extensions are possible.
  • Video playlist reader and Hap playlist reader nodes were introduced. Together with Filepaths from folder node, they can play all the videos in a folder.
  • Image slideshow reader node has been introduced. It works in conjunction with Filepaths from folder node and creates a slideshow out of all the images in the Filepaths input. Fading between images and zooming in or out is possible.
  • JSON parser and JSON packager nodes were introduced. JSON parser converts an incoming JSON stream into Lightact values. JSON packager, packages Lightact values into a JSON stream.
  • Node search function in the right-click menu has been improved.
  • New string processing nodes: String substring (finds the position of a substring), String length (outputs string length), String lowercase, String uppercase, String add (concatenates 2 or more strings).
  • MIDI reader: a new reader node in Devices window together with MIDI listener node in Layouts, allows you to control Lightact with an incoming MIDI signal.
  • Intel RealSense reader: a new reader node, together with RealSense listener node in Layouts, allows you to receive RGB and depth streams from Intel RealSense cameras.
  • Spout reader: in Spout reader, we fixed a bug that caused a sporadic flickering of incoming texture.


  • LightNet allows you to find other Lightact devices on the network. It’s useful for LightSync and for future upgrades regarding multi-server situations.
  • LightSync is a messaging system allowing for multi-server syncing.
  • New asset management system: Lightact now makes a local copy of all imported assets in the project folder. This will make it easier for future project syncing along multiple servers connected through LightNet.
  • New welcome screen: it features new sample projects and What’s new section giving you updates on new content on Lightact Support website.
Layer Layouts
  • Video file reader node now has several new inputs: Volume, Start at and End at and Ignore pause; and outputs: Frame number, Position, Duration and isPlaying. These new features allow you to create much more flexible video playback action flows.
  • Render to canvas node now has Opacity input.
  • Fade in & out nodes: there are several new Fade in and out nodes based on layer time or sequence time. These allow you to more quickly create content that fades in and out based on show parameters.
  • Interpolation nodes: we’ve added 4 new interpolation nodes for floats, vec2, vec3 and color values.
  • Optical flow node now has a Min val parameter, which helps eliminate noise with low movement feeds.


  • NDI Server & Client: you can now send and receive textures using NewTek NDI.
  • Spout status is now visible in Devices window
Video playback
  • HAP codec: Lightact can now play Hap, HapA and HapQ encoded videos in .AVI containers.
  • Video looping: all video player nodes have now a Loop boolean input. If checked, the video will automatically start from the beginning when the end is reached.
Revamped particle system
  • 3D Particle System has been completely revamped. You can use texture emitters, 2 types of noise, adjust color and size over life and much more.
Texture processing
  • All texture processing nodes have a Passthrough option, which allows you to quickly enable/disable the node without having to (dis/re)connect it.
  • Color grading: Color grading texture processing node performs real-time color grading based on look-up tables (LUTs).
  • Chroma key: Chroma key texture processing node performs real-time chroma key removal. Also known as green-screen removal.
  • Glitch, vignette & scanlines: we’ve added 2 texture processing nodes (RGB shift glitch & Old TV look) which give you various options to introduce glitch, scanlines and vignette effect.
  • altogether there are 15 new texture processing nodes added: halftone, dithering, stippling and more can be found.
Texture generators
  • We’ve added a number of new texture generator nodes. They allow you to create new visuals on the fly. Examples include voronoi noise, bands, wavelets, color sine, checkerboard etc.
