Meta Quest Spatial Anchors | Create, Save, Erase & Load spatial anchors

[@mattpatterson8237]

Very nice video, I would love to see one on Shared Spatial Anchors!

[@Kingdomax]

Thank you, I'm exciting for what you could come up with shared spatial anchor tutorial.

[@marcelrebolledo9414]

Creating a video that showcases how to use "Shared Spatial Anchors" with Netcode for GameObjects 1.8.1 in a Unity project could be an excellent resource for developers looking to implement multiplayer features with a focus on AR (Augmented Reality) experiences.

[@blackwhalestudio]

Thank you for your suggestion!

Hello, thank you for your video, I follow the steps and created anchors, but I always got success=false in OVRSpatialAnchor.Save callback function. Donot know why

[@stevenle8969]

I am getting the same thing too. Did you figure out why?

[@I3ra]

How do you have these anchors persist in the unity editor while not in play mode? A use case, I want to reskin my room with a 3d model I created and textured, how would I get the room scale 3d model to match the physical room?

[@Doflamingo133]

Hey quick question if you see it and I am lucky. The spatial anchors work in editor but not in the build. Do you know why this could be happening?

[@sanky369]

Can we grab and move a prefab which is marked as a spatial anchor? I was not able to do it using building blocks. I had added both grabbable as well as spatial anchor to it.

[@blackwhalestudio]

I'm not sure about this. I haven't seen anything about moving anchors in the documentation yet. You might just need to delete an anchor and place a new one.

[@wingardiumLeviossa]

I tried to load anchors in the same session without quitting the app (my use case is to visually clear the anchors after saving and loading them on the user's command) - the resultant anchors-array from LoadingUnboundAnchors is NOT null but its length=0. Once I quit and reopen the app, the anchors are loading successfully. I want to load them before quitting the app (I mean in the same session). Any ideas on why this is not happening?? Or any suggestions on how to implement this?

[@McYvar]

Ayo! How did you get the spatial anchor creating working in Unity itself? Each time, when the prefab is instantiated, the OVRSpatialAnchor script tries to create the anchor but fails to do so even though it does work on a build in the headset itself. So how exactly did you manage that?

[@blackwhalestudio]

Check if you enabled spatial data over meta link in your meta link app's beta features!

[@kimfaiyim]

This is a great video！ Thank you! However, there is something update in the SDK and somehow I can't get the pose of the anchor. I get error like " Anchor must be localized before obtaining its pose" from the code "var pose = unboundAnchor.Pose;". Could anyone give me some help on this problem

[@MohammadRezaMohammadi-c6d]

why do i get this error in step 2: [OVRSpatialAnchor] OVRPlugin.CreateSpatialAnchor failed. Destroying OVRSpatialAnchor component. UnityEngine.Debug:LogError (object)

[@TheXSaiko]

Cause now don't work in unity runtime, u need build and test with apk in oculus

[@strangefuture]

Could we in theory use this logic to save a game scene on a wall/floor or table of the players choosing, and then be able to play the game after the anchor is placed?

[@starmoon-m7s]

mruk is now depricated what should we use instead? i am unable to find the MRUK prefab...

[@blackwhalestudio]

MRUK is not at all deprecated. It has slightly changed but is now better than ever.

[@citan554]

Now Meta says LoadUnboundAnchors is obsolete, and to use the Async version of that method instead

[@coverscollection8775]

I cant save the anchor 15:57:05.350 Unity [OVRSpatialAnchor] OVRPlugin.SaveSpaceList failed with error Failure_InvalidOperation. 15:57:05.350 Unity OVRSpatialAnchor:Save(ICollection`1, SaveOptions, Action`2) 15:57:05.350 Unity OVRSpatialAnchor:SaveBatchAnchors() 15:57:05.350 Unity OVRSpatialAnchor:LateUpdate()

now Save command is deprecated need change to SaveAnchorAsync

[@TheGameLecturer]

should it work in editor?

[@blackwhalestudio]

Yes!

[@TheGameLecturer]

@@blackwhalestudio Thanks for the answerer, for some reason it doesn't work for me right now but knowing it should work in editor might help the debugging process.
