[SOLVED] OVR enabling / disabling "use per eye cameras" makes no différence on Oculus GO

Hi folks.

I'm trying to achieve the brackey portal tutorial -> in VR for oculus go.
The portal is a plane with a rendertexture displaying what an other duplicate camera sees.

In order to see the perspective correctly through the portal when the player moves, I must use some stereoscopic tricks.
So I'm setting up 2 planes collapsing on each other, and my plan is to display on plane per eye.
On for the left eye and the other for the right one.

I managed to set the layer system, and I can see that it works on each camera views ( left and right eye anchors ), but after building, there's no différence between what's displayed on my left or right eyes.

I tried several time to check / uncheck the "use per eye" box under the OVR Camera Rig script, but nothing append.

Am I missing something or is it a bug?

Thanks a lot.

 

In fact, I just build the wrong scene... so everything's seems to be fine with "use one camera per eye" option.
