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.
Exporting and importing spaces data
We are sharing world anchor data to create a shared experience on HoloLens. For the most part, this works pretty well. However, we have found that sometimes a device cannot anchor a world anchor exported by a different device. We have found this to be because the space data on each device is different (if we clear the space and rescan, it can then position the anchor).
So, we are wanting a single HoloLens to scan the space and export the world anchors, then other devices load the space data and world anchors. Conceptually, this presents a much more bullet proof option than having all the separate devices have their own scans. It is also much easier when introducing new devices to the environment-- they don't need to scan.
Then the question is: can we export and import the HoloLens space data?
