HMD Roll and Particles
I'm trying to find a solution to particle effects rolling with the OVR. The issue is that camera facing particles rotate the same direction as the camera so when you tilt your head, the particles rot...
Good quesiton. And honestly I don't recall any game that wouldn't have particles rotated to match your UP-vector.
I think you can measure the angle of the HMD against some up-vector, and put negative of this value as an orientation parameter in the particle system. Both individual particles and particle system as a whole have rotation property.
