We can stay longer at the end of the meeting and discuss the details. The SDKs on github have unfortunately not been updated for logistical reasons (access rights), but I can provide you with zip files which you can download. I don’t want to post the links here because they will become invalid soon. However, you may not actually need to download them depending on what you want to do exactly. But let’s discuss that next Wednesday.

The short answer is yes, you can create your entire project in the Unity editor and later adapt it to run in the Portal Hopper.

We have reviewed the provided resources, including the latest versions of World Builder and Portal Hopper, as well as the toolkits on GitHub.

Given the problems we faced in working with the Builder (which you are well aware of), most of our efforts have focused on building in Unity, hoping a migration path would soon be available. A hopper-developer-sdk has been recently made available on GitHub. However, we could not find detailed documentation or examples explaining how to properly integrate and use this SDK within a Unity project.

Could you kindly provide us with more specific guidance or documentation on:

How to integrate and use the hopper-developer-sdk inside Unity?
Whether it is possible to implement our pilot entirely within Unity and have it fully supported by the XR4ED platform (e.g., compatibility with the Portal Hopper)?
Additionally, if there are example projects or sample scenes we could use as reference, this would be extremely helpful.

Thank you in advance for your support!

However, did you try using the search box at the top of the Logic Editor page? It might be useful in such a situation, because it will jump directly to the selected node if you click on the found items in the drop down menu.

I’ve noticed that when zooming out inside the Node Group, zoom is behaving strangely.
It zooms out to a random place, and it’s difficult to find the nodes. I need to exit the node group and return to reset the view inside the flow graph of the node group.

The starting point is determined solely by the Start Avatar.

If Possible Please guide how can I achieve that.

1. Have used a simple cube for floor
2. Have added a button to jump into other location
3. created the signal of the button
4. in logic editor i have used button, if and chnage location node
5. Button is click if its true chnage location triggers
6. Change location, external location is used and the link to my vrml file that is put on local server is given
7. For Main location link to location 2 is given and for location 2 link to main locations vrml is given

I started the main location vrml file and clicked the button it jumped to location2 and same way in location2 clicked the button and I came back to main location.

When coming back to same location the floor disappeared and if i go again to location2 the floor is also gone from there.

Simply the changing of location works once going back and again going to second location foor just disappears.

The fix will come in the next Release (most likely Monday, 30th of June)

The Raycast Object Node ray casts only the top parent object, regardless of the state of the “Only Top Level” checker.
This is causing us huge problems because, without gaze data, our adaptive learning algorithm doesn’t work.
I hope this can be fixed in the next update. 🙏
Thank you!
Raycast Object Only Top Level
