I launch the project directly from unity and get the passthrough on the headset

Do you mean build and run or just Play on Unity?

Hello, sorry for the misunderstanding, I play on Unity yes.

Hi @Virtus,

Could you try build apk and see if ScenePerception works?

ScenePerception will not work if you Play on Unity Editor.

Ok, I will try it. Do you know if there is any possiblity to run it directly on Unity ? The fact that I need to build and upload to the headset each time would be really time-consuming.
If there are no other way, then i'll do with it, but I just want and need to know perfectly how it works.

So,

I built an APK, and I added some debug informations in the scene to display informations such as Nbr. of meshes retrieved and planes retrieved.
There was still 0 mesh and 0 plane retrieved.

I don't know where it could come from.

I am using this method :

scenePerceptionManager.GetSceneMeshes(currentSceneMeshType, out WVR_SceneMesh[] currentSceneMeshes)

and currentSceneMeshes.Length returns 0.
I have scanned the room with the headset,  and gave authorization for Scene Perception.

Hi @Virtus,

Are you testing with SDK's sample scene?

[Virtus]

Hello,

No, I am directly testing on my own scene. I could retrieve scene planes but still no scene meshes.
I am focusing on what I can retrieve now, so I am managing the Scene Planes.
Issue is now that position and rotation doesn't feel right.
I display the planes directly on the scene from the data I retrieve, using WVR_Pose_t data, or ApplyTrackingOriginCorrectionToPlanePose() function.

It doesn't seem like data we get fits with reality distances.

Hi @Virtus,

Could you test with SDK's sample scene(ScenePerceptionDemo(SceneMeshAnchor)) to see if it works?

[Virtus]

I tested, and the Demo scene displayed the meshes successfully !
Now I need to know how and why it was not working on my project.

 

Thanks

Hello,

 

So I did a few tests, I could retrieve scene meshes and scene planes, but could not retrieve both at the same time. I also tested with the demo scenes.
It seems like when I activate both scene planes and scene meshes, the scene planes takes the priority on the display, resulting in no scene mesh displayed.

Best regards
