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...
You will see this with any particle texture that is not radially symmetrical, with any combination of particle system parameters, as long as you use the billboard render mode (which you almost always do).
Its a natural consequence of the particle billboards aligning with the camera that they do not maintain a consistent up vector. It looks fine in most games because they don't let you roll the camera, but special handling is going to be necessary in VR.
