Resolved Error in Runtime Reference Image Library

Hi I'm new to Unity and i'm trying to add new reference image at runtime.

https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@4.2/manual/tracked-image-manager.html
I saw some way to add runtime reference image in this page but it don't works exactly.

here is my code

Code (CSharp):

1.  if (arTrackedImageManager.referenceLibrary is MutableRuntimeReferenceImageLibrary mutableLibrary)
2.         {
3.             Debug.Log("ReferenceImage Added.");
4.             jobState = mutableLibrary.ScheduleAddImageWithValidationJob(markerImage, "keypad", 0.07f);
5.             Debug.Log("Image Library Count : " + mutableLibrary.count + jobState.status + jobState.ToString());
6.         }

ScheduleAddImageWithValidationJob method always return jobState.status.ErrorUnknown and i don't know why it returns error. can anyone tell me why?

 

Now I figured it out. It returns error when I add runtime library while AR Session is not ready.

 

Hi @CheolSoonKim, can you tell me when how to make AR Session Ready?
