Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

Sharing, anchors and remoting

Unity: 2018.2.0f2
HoloToolkit: 2017.4.2.0

Due to processing needs, we have to execute our app in a PC and connect to Hololens using remoting.

In a light version of the project, we tested the sharing system that work properly using 2 hololens.

The problem is that when we move to remoting version of the project, anchors are not shared. Sharing and messages work, they are sent and received, but world is not correctly aligned because of the problem with sharing anchors.

Diving int the code, there is an async call that never resolves:

[WorldAnchorManager.cs]
protected virtual void Start()
{
WorldAnchorStore.GetAsync(AnchorStoreReady);
}
We guess this is not supported on remoting, nor on UnityEditor.

Is there a workaround? Any other way to share anchors and align world coordinates in remoting + hololens?

Thank you

    Indeed, as you comment, the use of Anchors is not compatible when remoting is being used, as discussed here: https://github.com/Microsoft/MixedRealityToolkit-Unity/issues/274#issuecomment-254274307. Two comments below is proposed to calculate the anchors from the origin, without using the Anchors itself - I have sincerely never tried this method, but it would be rewriting the functionality of Anchors. What is perhaps strange is that the async function does not end correctly.

    What do you understad by "calculate the anchors from the origin"?
