Overview
For best performance, run the LIGR NDI software on the same computer as your main application. If necessary, it can also run on a separate machine connected to the same network. This article explains how to generate the graphics overlay in vMix.
Prerequisites
Access to the LIGR Google Drive download link
Windows computer on the same network as vMix
LIGR Production URL
Step 1: Install the NDI Application
Download the NDI App and Windows Installer from the LIGR Google Drive
Run the installer and follow the on-screen instructions
(Optional) Create a desktop shortcut for easy access
Step 2: Launch and Configure the NDI App
Open the NDI application
Set your Canvas Size
Recommended: 1920 × 1080
Choose your Frame Rate (FPS)
Paste your LIGR Production URL
Enter a clear, descriptive NDI Source Name
This helps you quickly identify it on your network

Click Start
Your NDI output is now live on the network
Step 3: Add the NDI Source to vMix
Open vMix

If there is a GFX On Air in the LIGR Control Room then it will appear on the input window in vMix and the BlackMagic Card can be configured to output with Key & Fill via the External settings. An article explaining how to configure vMix and a Blackmagic Design card to generate Key & Fill output can be found here.
