The answer, sadly, is no. The automatic VRML file generation is not up to date because we keep making changes and never have the time to update the VRML generator. To all who wish to

  • use Unity and asset bundles with the Portal Hopper (PORTAL_HOPPER_PROTOCOL)
  • launch an external app (installer) via the Hopper (DOWNLOAD_AND_RUN_PROTOCOL)

please contact me via email for further assistance.

Thank you for toolkit – I need to check what it contains 😉
For option A – how to create VRML file?
For option B – I assume I need to create one aaset bundle for whole application or separate asset bundles for each scene? And I can use a Create VRML file option inside Unity for this, right?

Cheers,
Marek

And there is no defined screen space since the Portal Hopper can run on a standalone headset which has no screen. So, the PH actually always has a screenspace version and a headset version for all UI interaction. The World Builder does not support that, at least not currently.

In that case you have two options how to proceed.

a) create a standalone app which is launched from the hopper but does not run in the hopper. To do this, you need a vrml file which defines a DOWNLOAD_AND_RUN protocol and you need to create a single executable installer which can install your app and register it in the registry.

b) create a scene asset bundle (Unity only) and one or more DLLs which contain your scripts. This can run inside the Hopper. To do this, you need a vrml file which defines a PORTAL_HOPPER_PROTOCOL protocol and must create the scene asset bundle(s) from your app. You’ll also need to get the Designer and Developer toolkits for the Hopper, at least to gracefully exit your game, but you’ll also find other useful scripts in these toolkits (very beta version). Let me know by email if you want to go this way so I can provide the three corresponding packages to you as zip files.

If you must publish an APK, you have to do it outside of the XR4ED environment through one of the registered VR publishers. For versions a and b, you upload the vrml file to the shop but place your asset bundle or installer on your own server/domain.

Can new HUD elements be created in the WorldBuilder and placed in screen space on Canvas?

Thank you.

The only workaround I can think of is to restart a timer every time a value change is received and to evaluate it as a release after a timeout has occurred.

We are developing a VR standalone application using Unity and we want to distribute it in XR4ED marketplace. It will be in APK format.
How can we publish it in XR4ED Marketplace?
Is there any plugin, SDK or sometnig else to include in our APK to integrate with marketplace?
Or it is just upload file to marketplace and that is all?
In documentation we have found a instructions such as:
develop your app from the ground up or based on a different game engine, then you’ll need to implement our portal mechanism as specified in our VRML Specification.
Where we can find this specification?

We were consulting this with mentors, and heard, that there are more teams struggling this situation

At then moment I can only detect the knob Value OnValueChanged. Is there a way to detect when the Knob object was released?
I want to activate other logic only when the Knob is released, and the value is set to the correct value.

Thank you.

Then use the SkyBox Video Node to switch between different videos, depending on which bubble you are leaving/entering. Mixing 360° videos and 360° images is a bit more difficult, because the images are displayed by projecting them onto a sphere while the videos are fed to the skybox. You will have to do some hide/show instructions to get the desired result.

I am interested in using 360 vidéos and images. I would like to use them as skybox and like bubbles an avatar can walk inside and out.
There is a way to use multiple 360 images/vidéos in the same world ?
