Notch to Lights
Add an NDI Output node to a Notch block and drive lighting fixtures in Spectralite from real-time Notch content.
Notch content usually plays on an LED wall through a media server. The fixtures around that wall are programmed by hand, on a desk that cannot see the video. When you add an NDI output in Notch, Spectralite reads the render. The surrounding rig then picks up its color and movement.
Add an NDI Output node
In Notch Builder, add an NDI Output node from the Post-FX section under Image Processing. Attach it to the video or scene render that you want to publish. Notch then sends that render over NDI.
A single Notch layer can drive several NDI outputs at once, so you can add a lighting feed alongside the outputs you already send. Notch documents the node and the protocol in its NDI reference.
Pick up the stream in Spectralite
Open Edit > Inputs > NDI. Turn on NDI input enabled and Auto-discover sources.
Put the video on your fixtures
For an immediate result, add a Timeline layer with the built-in NDI Input effect. For more control, wire an NDI Input node into an effect in the Node Editor.
Building a feed for the lights
You can attach the NDI Output node to your main render, but then it spends resolution on detail that no fixture can show. Build a second, small render path in the same project instead. Make it a low-resolution version of the look, or a simplified one that keeps the palette and the motion without the fine texture. When you publish that path, the rig follows the piece and the wall keeps the full render.
A separate path also keeps the lighting feed stable when the main render changes. If you reframe the wall content, the colors that your fixtures read stay where they are.
