Holographic Emulation in Editor room spatial rendering

Hello, for some reason i am not able to use rooms in holographic Emulation any more. Neither with Unitys render components nor with mixed reality toolkit.

I have falls creators update installed and unity 2017.2.0f3 running (cannot go higher as i used a Version of mr toolkit only compatible with this and a color separation issue with later unity versions).

Build Settings is set to UWP / HoloLens. Playersettings have XR SDK set to Windows Mixed Reality and spatial perception is on. Holographic Emulation is set to "in editor", a room is selected. An XBOX Controller is connected.

Entering playmode lets me move the camera via the xbox Controller. But i never see one of those dummy rooms.

Also added a gameobject with "Spatial Mapping Renderer" and "Spatial Mapping Collider". But nothing happens. What did i miss or what is the Minimum Setup to see a room in the Editor?

Besides this the console often (but not always) gets flooded with:

• Couldn't find spatial stage - we have to track as though we were stationary for our tracking space type, even though we should be at room-scale!
• Current frame's back buffer doesn't exist! This should never happen, and this frame will likely be blank.
  

 

Hm, found a 2017 Version of MS Origami example only using Unity components: https://github.com/Microsoft/HolographicAcademy/archive/Holograms-101.zip

This also shows no rooms in Editor Emulation. Works however as expected in VS2017 HoloLens Emulator.

So, what´s the Point then with in Editor Emulation???

 

After trying it yesterday half the day, for unkown reasons the room meshes of the Origami Scene show up today under:

Version 2017.2.0f3 (46dda1414e51)

Branch: 2017.2/release

Also works under 2017.2.1 - i didn´t Change anything. Need to check holotoolkit now.
