VRCOSCdesktop is a software that uses VRChat's new OSC Open Beta update to make an interaction between this software and VRChat, enables the program to seamlessly control the Animation Parameter of VRChat avatar, and much more in the future. Currently (Version 1.1) VRCOSCdesktop supports controlling partial of VRCLens Settings, makes control much more easier than using a radical puppet. Also includes support for VRLab's Marker. Picking color, controlling the size, and attaching a drawing on the body part is a lot easier. VRCOSC project aims to become a simple but powerful bridge between VRChat and external program. Your support and suggestion would be really helpful for the development.
