ARCore Cloud Anchors Blueprints

Hello community,

I got some questions about ARCore in Unreal Engine 4 especially Cloud Anchors.

My group and I want to develop a game via ARCore in which up to 4 players can play against each other.

For this we want to use the Cloud Anchors.
However, the question arises whether we should bind the characters to a common anchor or for each character you have to create your own anchor.
Unfortunately we haven’t found a way to attach the characters to a common anchor yet and would be happy about a tip.

Also the question arises whether the anchor updates itself as soon as a character moves or whether we have to replicate it manually on each device.

Thank you in advance everyone!
