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 messaging to third-party apps. For projection work, it offers 3D mapping with camera-projector calibration, manual warping and blending. Multi-server clusters can distribute workloads and synchronize frame by frame. Integrations include Notch blocks, TouchDesigner components and Unreal Engine, alongside content sources such as Deltacast, Blackmagic, NDI and Spout. It also supports OSC, TCP, UDP and TUIO messaging, plus third-party camera and object tracking with a Tracking Visualizer. Its customizable browser-based WebUI is available only on LightAct servers. LightAct is self-hosted on Windows; documented minimum requirements include Windows 10 or later, a discrete Nvidia graphics card and at least 8 GB of RAM. The free Creator plan unlocks all features and unlimited outputs, but adds watermarks. Easy Perpetual costs 1,770.00 EUR once.
