Run it
Copy the script and paste it into your executor.
loadstring(game:HttpGet("https://raw.githubusercontent.com/UltramixSecondDev/R6-Rig-EditorBeta/main/BetaRigStudioR6.lua"))()Loads code from the internet. It downloads more code when it runs (loadstring + HttpGet), which can change after it was posted. From: raw.githubusercontent.com.
If you're on a mobile device, I recommend setting the screen to 600 dpi for a better experience for now; it's not mandatory, just optional. The animator for the R6 rig is here; it's basic but functional. It has a few bugs, but I'll fix those later.
