I want to use PSVR with blendergame. The game renders full screen in SBS 3D. In the Trinus PSVR help tab ‘setup’ it says “mouse mode…make sure its SBS…” but how do I set “mouse mode”?

In cinematic and cinematic track I see the side by side video on a big screen, Steam VR, VR conversion, Legacy VR conversion show me a black screen. Looks like I need mouse mode but can’t find it.

(I have it working in Trinus cardboard to my phone, I would like to get the PSVR working.)
thanks
