The Mixed Reality Forums here are no longer being used or maintained.
There are a few other places we would like to direct you to for support, both from Microsoft and from the community.
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.
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, or in our Microsoft Tech Communities forums at https://techcommunity.microsoft.com/t5/mixed-reality/ct-p/MicrosoftMixedReality.
And always feel free to hit us up on Twitter @MxdRealityDev.
Different coordinate systems
I'm trying to use network transforms to synchronize moving objects. But a network transform sends position/movement information relative to the current device's coordinate system (in which the origin is located at the position of the HoloLens I think?). Another HoloLens has a different coordinate system and so the synchronization doesn't work.
It sounds like Spatial Anchors are what I should be using, but I can't figure out how Network Transforms and Spatial Anchors can work together.
