When streaming a prediction game on Noice, they fall into two categories: Validator or Game Connect App.
Currently, League of Legends, Valorant and Marvel Rivals use the Game Connect App. You can find a helpful guide for it here: Noice Game Connect App.
All other prediction-compatible games use a Validator, which requires some setup in OBS.
Noice OBS Plugin
First, you will need to download and install the OBS plugin.
You can find it in the Noice Studio, under Settings > Stream.
Adding the Noice Validator to a scene
In order for the Prediction game to work properly you should add Noice Validator as a source.
Open a scene that you use in-game and add Noice Validator as a new source to your scene.
Click OK to create the validator.
Double click on the Noice Validator Source.
Choose a game you want to stream on Noice from the dropdown menu.
Check both Show all Noice regions and Show all OBS source candidates checkboxes to show all sources and click okay.
Make sure to move any existing overlays and cameras away from the solid orange boxes.
You’ll know if something is blocking them because the box will turn yellow and flash.
Once you’ve adjusted everything, you can click the eye icon on the Validator source to hide it.
