LIU (Light It Up) runs on Unreal Engine 4 and works together with a branch of SPOUT tech created by the team at Off World Live that allows for streaming through programs such as OBS. This let's users to show off their unique arcade layouts to their audiences even when the program is minimized.


To get LIU running on OBS 1. Make sure your OBS version has been updated to the latest version. (At least version 28) 2. Install the Spout2 plugin for OBS-28 (The file is available inside the 'Install' folder) 3. Run LIU_Overlay.exe 4. Run OBS and on any scene, add a new 'Spout2 Capture' source. 5. The LIU controller should appear inside. 6. Have fun!


LIU (Light It Up) is being developed by Australian 09er Peter Phan (pdcsky), a 3D artist turned unreal engine developer with over 8 years of experience. It had initially started off in 2020 as a hobby project, spurred out of pure salt that no such controller visualiser existed at that time and has now grown into a full blown app ready to be given to the FGC!
