As of 26/07/2022 VRChat released an update which includes a kernel anti-cheat known as Easy Anti-Cheat, this makes the usage of mods impossible. While this may stop mods that can be used maliciously such as force clone, it also stops users from using mods that are actually necessary to improve the game's qol. If you are looking for alternatives to this game, feel free to check out ChilloutVR.
A melonloader mod that allows you to clone public VRChat avatars without the target's permission.
Before install: Remember that any modification of the game can lead to a ban.
To install this mod, you will need to install MelonLoader 0.5.3. Then, put the ForceClone.dll file in the Mods folder of your game directory.
Drop the required libraries (you can found them in <vrchat install dir>/MelonLoader/Managed after installing melonloader) into Dependencies folder.
