The [multiplayer] beta branch just received a MAJOR update.
To try out SculptrVR multiplayer today, you need to opt into the [multiplayer] beta.
Library -> right click SculptrVR -> properties -> betas -> select multiplayer from the dropdown
You'll know you've successfully opted into the beta if your game looks like this:
You can host public/private games. Invite friends on Steam, and then sculpt together!
There are still some bugs left, but huge strides are being made daily! Multiplayer will probably be released on the main branch in the next week or so.
Have fun! I hope to see you in SculptrVR!
