LightAct vs Mapping Matter

LightAct combines software and hardware for live events and immersive fixed installations, including projection mapping. Its Layer Layouts support video and audio playback, conditional logic, and messaging with third-party apps. The 3D mapping workflow includes 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. Network messaging supports OSC, TCP, UDP, and TUIO, and the software supports third-party camera and object tracking. Its customizable WebUI runs in a browser but is available only on LightAct servers. LightAct 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 free Creator plan unlocks all features and unlimited outputs, but outputs are watermarked. Easy Perpetual costs €1,770, paid once; the Live Perpetual price is available by request. LightAct does not support sending or receiving interlaced video streams.
