Is there some tricks to know to have a full working head tracking ? What

The client 3D window still has an impact on scene that is to be able to use
the client as a sort of a controller to not only set the pipeline also to
move things around (for using a tablet  to drive a cave etc). Head
 tracking (and HeadPose) primarily deals with the projection matrix and is
updated with each tracking input. Camera manipulations deals with changing
the model-view matrix. So head tracking does not disable the camera and all
other interactions should be possible.

Could you save out your pvx file and take a snapshot of the camera settings
and send the files to me?
