A weird issue(hololens):
When i start my app i am able to use the guide view to set my 3d Model, i put an anchor, i deactivate vuforia tracking and i deactivate the guide view via this function :
modelBehaviour.GuideViewMode = ModelTargetBehaviour.GuideViewDisplayMode.NoGuideView;
I have a button to replace the 3d model, when i click on it i reactivate vuforia tracking and the guideview with this function:
modelBehaviour.GuideViewMode = ModelTargetBehaviour.GuideViewDisplayMode.GuideView3D;
Every thing work fine but i lose the guide view, it blinks 1 second and disappear! When i print the state of the guide view with this command
print("guide view state = " + modelBehaviour.GuideViewMode), the result is "guide view state = GuideView3D".
So the guide view is active but it does not appear.
