It was recently discovered that the 3D Room Tag node had a few bugs in it. This was after some internal testing and some comments on the following forum discussion.

I am happy to say that this has been fixed and is now much more stable. The primary difference is the node now places the 3D Room Tag where the room’s origin is. (Similar to tag all)




You can of course find this on Dynamo’s package manger, under the latest Rhythm update
