Any VR explorers noticed this problem?
Hmm, just passed through a system with a spinny boy the other day, but moved on before observing anything..
I have however noticed what you have reported before, about anamorphic lens flares shifting vertical position with head rotation -. probably down to its Z offset, combined with one of the the unsuitable tracking behaviours we see such a lot of with sprites...
I usually play with lensflares turned off, because I just don't think they are a realistic effect, and quite annoying to have, unless one think of oneself as a camera lens, rather than a living being. Unfortunately a lot of emissive effects are lost together with them, if turned off -. stars look less blinding, and toastrack positional beacons become exceedingly hard tp see.
..but, now, if one absolutely IS to have lens flares, then I can't deny that it is correct behaviour for
them, specifically (but not other things) to do all of: 1) rolling along with the camera, 2) Glaring out everything in one's view, including ship interior - the effect mimicks glare either in the camera lens train, or in micro scratches in one's helmet visor, and 3) Going out entirely, momentarily, in any eye view in which the originating light source becomes occluded, e.g. by a canopy strut. (When this happens with the glare from a nearby star, that reveals a smaller, otherwise identical sprite, which represents the star's corona, and which promisingly
doesn't roll with the camera!).
