This page lists the current Unity version you should use when creating content for VRChat, as well as linking to the documentation for our Creator Companion.
Current Unity Version
Ensure you are using this exact version! Using a version newer than our current supported version may permit you to upload, but you won't be able to see your content in VRChat.
We strongly recommend using the VRChat Creator Companion, as it takes care of choosing the correct Unity Version for you. It also keeps the VRChat SDK and community-made packages up to date.
