Hi,
pun v2 is really just the same as pun classic, only that under the hood there was a lot of cleanup, so technics from Pun classic still apply largely to v2 really.
in the video, what you see is the two clients, and so player controlled in the editor is moving on the second client, I don't see anything odd there, that's how it's supposed to work.
same with raycast, there isn't anything different in the way you need to think your system between classic and v2.
Bye,
Jean
