在虚幻引擎 4.26 中创建天蓝色的空间锚点

Question

So I just finished implementing the spatial anchors functions found on the microsoft documentation, but it doesn't show how an anchor is made after placing all of the functions in the blueprint. I was wondering if anyone can help out with this kind of thing. If possible can anyone point me in the right direction cause all I can find were tutorials on using spatial anchors for unity but not unreal engine. The image shows what some of my blueprints look like for implementing spatial anchoring for the hololens

Adding answer here for reference from Q&A.

Check the branch after CreateSession:

You should connect the return value of CreateSession to the branch, otherwise ConfigSession2 will never be called:

Take a look at our OpenXR HoloLens sample project here: https://github.com/microsoft/Microsoft-OpenXR-Unreal You can see how we set up Azure Spatial Anchors in the StartASA function in the MRPlayerPawn blueprint

Some other differences/ things to check:

1. Expand the tab in MakeAzureSpatialAnchorsSessionConfiguration and set the Account Domain from your Azure Portal.
2. Set the Log Verbosity in ConfigSession2 to All to see if any warnings are preventing the setup from continuing. Also view your output log to see if any errors are being logged.
3. The False branches should either log a failure or retry after some amount of time:

4. In Edit > Project Settings > HoloLens > Capabilities, verify you have enabled: "Internet Client Server", "Private Network Client Server", "WifiControl", "Spatial Perception", "Proximity", "Location", and "Bluetooth"
