LightAct

What LightAct 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 messages to third-party apps. The 3D mapping workflow includes camera-projector calibration and manual warping and blending tools. Multi-server clusters can distribute work and synchronize frame by frame. Integrations include Notch blocks, TouchDesigner components, and Unreal Engine; content I/O options include Deltacast, Blackmagic, DirectShow-compatible sources, NDI, Spout, and Unreal Texture Share. It supports OSC, TCP, UDP, and TUIO messaging, plus third-party camera and object tracking with a Tracking Visualizer. The customizable browser-based WebUI is available only on LightAct servers. The software is self-hosted on Windows; minimum requirements include Windows 10 or later, a discrete Nvidia graphics card, and at least 8 GB of RAM. The Creator plan is free, unlocks all features and unlimited outputs, but watermarks outputs. Easy Perpetual costs 1,770.00 EUR once; Live Perpetual pricing is by request. LightAct does not support sending or receiving interlaced video streams.
