MiddleVR, head tracking: only translations, not rotations ?

Hi everyone,

I hope the title was explicit, I’m developping a VR application using middleVR, the hardware used is: 1 stereoscopic screen (2 projectors), 1 flystick and head tracking on the 3D glasses.
Everything works, except I’d like to lock the camera on translations and avoid rotations. It would be fine in a cave system, but here I just want to be able to slightly go aside and crouch.
I didn’t find how to do that in MiddleVR configurator, and I have not enough knowledge in C# to modify the provided scripts.
Can someone help me with that ?

I solved this by selecting “Screen0” for the option “Screen” in the MiddleVR configurator (was undefined)
