Ljubljana, Slovenia
What it is
LightAct is software and hardware for live events and immersive fixed installations, including projection mapping. Its Layer Layouts combine video and audio playback with conditional logic and messaging to third-party apps. The projection workflow uses 3D mapping, camera-projector calibration, and manual warping and blending. Multi-server clusters can distribute workloads and synchronize frame by frame. Integrations include Notch blocks, TouchDesigner components, and Unreal Engine; content I/O includes Deltacast, Blackmagic, DirectShow-compatible sources, NDI, Spout, and Unreal Texture Share. It supports OSC, TCP, UDP, and TUIO messaging, along with third-party camera and object tracking. A customizable browser-based WebUI is available only on LightAct servers. The software is self-hosted on Windows, with minimum requirements including Windows 10 or later, a discrete Nvidia graphics card, and at least 8 GB RAM. The free Creator plan unlocks all features and unlimited outputs, but outputs are watermarked. Easy Perpetual costs €1,770 once; Live Perpetual pricing is available by request.
