Here's a guide to OBS setup for the plugin by toothboto#3030

Fully customizable in game overlay

All stats are accessible from f2 -> plugins -> Stat Counter
See from 1-10 stats at once, with any color text and background. You can also rename the stats, for example it can display "Game Demolitions" as "Demos".

Custom fonts

The plugin now supports custom fonts. By default it uses the Ubuntu Regular font.
If you want a custom font for the overlay, first close Rocket League.
Open the fonts folder at %appdata%\bakkesmod\bakkesmod\data\fonts\
Replace OBSCounter.ttf with any .ttf font of your choice, renamed to OBSCounter.ttf

Known Issue
Ragequitting casual games messes up the games tracking. You must wait until the end of games for the plugin to count them. It was really hard already to get the plugin to support casual games and joining matches in progress, so this issue is unlikely to be fixable. If you want to reset your most recent game stats, just press the add a game button in the f2 -> plugins -> OBSCounter menu.
