At the current moment, Replay Mod does not see movement coming from Vivecraft, and ignores them when recorded and played back, making it show like a normal character. It would be great if you would be able to read incoming to record movements so then everyone in the Replay Mod recording would be recorded properly. This would mean adding a hook into Vivecraft Mod to grab movement data.

TLDR:
Vivecraft doesn't have movement in recordings.
I would love them to be added.
