User \ Observe
These two nodes let one participant in a shared VR session follow along with another — for example so a trainee can shadow an instructor, or an instructor can keep an eye on a trainee. Start with Observe User and end with Stop Observing.
Observe User
Lets one participant start watching another participant in a shared VR session — following along with what that person is doing.
What it does
In a session with more than one participant, this node makes the chosen Observer begin observing the chosen Observed User, so the observer can follow that person around the scene. It’s the natural partner of the Stop Observing node: observing carries on until you stop it (or start observing someone else). A common use is letting an instructor or a new participant follow an expert as they move through a training scene.
This only changes what the observer is following — it doesn’t move, change, or affect the person being observed in any way. Both participants come straight back out of the node, so you can keep working with either of them in the nodes that follow.
Inputs
| Port | Type | What to connect |
|---|---|---|
| Execute | Trigger | Wire this from the previous node’s Execute output. |
| Observer | User | The participant who will start watching. Choose Host Only for just the host, or All Users to have everyone start observing. Defaults to Host Only. |
| Observed User | User | The participant to be watched. This is always the Host Only participant. |
Outputs
| Port | Type | What you get |
|---|---|---|
| Execute | Trigger | Fires once observing has started. |
| Observer | User | The same observer you chose, passed along so you can use them in the next node. |
| Observed User | User | The same observed participant, passed along so you can use them in the next node. |
Example
| Observer input | All Users — everyone starts observing |
| Observed User input | Host Only — the host is the one being watched |
| Observer output | The same participants, ready to chain into another user node |
Tips
- Pair this with the Stop Observing node when you want a participant to stop following and return to controlling their own view.
- To switch who someone is following, just run Observe User again with a different observed participant — you don’t need to stop first.
Stop Observing
Ends the “follow another person” view for a participant, returning them to their own viewpoint.
What it does
When a participant is observing someone else — seeing the scene through that other person’s eyes — this node stops that following. The chosen participant goes back to controlling and seeing their own view again.
This is the partner to the “Observe User” node, which starts the following. Use Stop Observing to release a participant once they no longer need to follow along. It only changes who that participant is watching; it doesn’t move anyone, change the scene, or affect the person who was being watched.
Inputs
| Port | Type | What to connect |
|---|---|---|
| Execute | Trigger | Wire this from the previous node’s Execute output. |
| Observer | User | Choose which participant stops following: Host Only or All Users. This is the person whose view returns to normal. You can also wire in a User passed along from an earlier node. |
Outputs
| Port | Type | What you get |
|---|---|---|
| Execute | Trigger | Fires once the participant has stopped observing, so you can continue to the next node. |
| Observer | User | Passes the same participant along, so you can chain more user nodes after this one. |
Example
| Observer input | Host Only |
| Observer output | The same participant, now back to their own view — ready to pass to the next user node. |
Tips
- Pair this with the “Observe User” node: one starts the following, this one ends it.
- Pick All Users to bring everyone back to their own view at the same time — handy at the end of a guided walkthrough.
