Moving around 3D space with Samsung Odyssey+

Hi there,

I am brand new "user" of unity. I have a simple goal, doing immersive VR visits of 3D models.
(Unfortunately, I am not much of a programmer.)

I am able to import my point clouds into unity (that's fine) but I can't navigate within my model in VR with the odyssey+ controllers.
If I don't connect the VR glasses and go into "play" mode, I can move around my model using the arrow keys of the keyboard, if I connect the Odyssey+, and then, enter the play mode, I do see my point clouds, but can't move around anymore (not with the keyboard, not with the controller).

I have installed the Windows Mixed Reality Toolkit, but I am a little lost as to what to add to enable simple navigation within my 3D model...
Could someone give me a hand to get started ?
Does anyone have a tiny project to share where navigating around (fly) a basic 3D model with Samsung Odyssey+ VR (Windows Mixed Reality) headset works ? That would help a lot to look at how it is made...

Thanks very much for your time and help.
Nico

PS... Do you think it is reasonable without C knowledge to takle virtual visits of 3D models with unity ? Thx
