It is a gimmick that allows you to attach an item (3D model) to your avatar with VRChat. It can be installed and used in a world created with Udon (VRCSDK3). At VRChat, avatar fitting sessions are held frequently, but I didn't have many opportunities to try on 3D models such as accessories. This was created with the goal of a system that makes it as easy as possible to try on a 3D model. It is provided free of charge, so please use it. The feather model and Unity-chan included in the usage example are not included in the product. The illustration-like feathers are sold by Momo-san. https://www.v-market.work/ec/items/1130/detail/ Unity is a copyrighted work of Unity Technologies Japan. © Unity Technologies Japan / UCL
You can install it in the world of VRChat and upload it. It can be used for both commercial and non-commercial purposes.
