v3.2.2

Released 26. July 2019.

General
  • Open Lightact projects by dropping .la project file on Lightact window.
  • Double clicking on .la project files opens them in Lightact.
  • Import assets by dropping them on Lightact window.
  • Layer templates.
  • Copy & Paste layers.
  • Console (similar to logs, but it doesn’t get written into a file – useful for debugging).

  • LightNet & LightSync total overhaul and upgrade.
Visualizer
  • Bloom (glow on glowing objects) is implemented
  • Primitive objects (sphere, cube, cylinder and plane)
  • Markers (objects suitable for marking locations of other objects)
  • Imported and primitive objects now have unshaded shading type which elimites shadows and makes them suitable for projection mapping.
  • Imported and primitive objects can grab textures directly from image assets.
  • New Visualizer menu allowing you to adjust visualizer settings in the Visualizer itself and not in Preferences window like before.
  • Objects can now display labels showing their names.
  • Holding shift while scaling objects by scale gizmo makes them scale proportionally.
  • There is an additional Keep aspect ratio checkbox in Throwers and Video screens freezing aspect ratio.
  • Projector range setting adjust the target’s location while maintaining the orientation of the projector.
  • Double clicking an object in the Visualizer tab, animates the camera to the object’s location in the Visualizer.
Nodes
  • CvMat Temporal Median: calculates median cvMat from a sequence (buffer) of cvMat images. Useful for eliminating noise from cvMats (such as depth images)
  • Quit application: this node quits Lightact, which is useful if you want to schedule a restart of the application. You need Lightact Manager for that.
  • Texture size:  returns the size of a texture
  • Print to console: prints a text to the console

eDMX (Art-Net) Fixtures
  • Overrides: In the Devices window, you can now, for every Art-Net node, adjust overrides. These override the content that is currently being sent to them.

Preset overrides allow you to turn the whole universe to full or off, whereas Channel overrides allow you to set the value of individual channels from Layer Layouts.
  • Art-Net Listener: Art-Net listener node has been improved so that it is possible to get a range of incoming Art-Net channels. You can then, for example, send them to Unreal Engine or do whatever you want with them.
Layer Layouts
  • Shared Memory Sender node can now convert and write an Array of Integers (useful for passing an array of DMX channels) and an Array of Floats (results of FFT analysis).
  • CV Canvas node has been improved to allow re-ordering of connected cvMats.

v3.1.1

Released 20. November 2018.

General
  • 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.
