[FONT="]Been working on eyes for the stealthy game. I’ve been trying for a while to emulate HL2/the Source engine’s approach to eyes in UE4: they’re not rotating sphere meshes with bones, they’re more-or-less flat planes with a shader on ‘em that points the iris/pupil where you tell it. It ends up being a lot less maintenance and it’s cheaper too (although the cost of those extra bones is probably negligible on most platforms). I’m not shader mathy enough to pull it off on my own; but Hoffman[FONT="] saved the day, with the help of an email from Ken Birdwell (the Valve guy who wrote all stuff for HL2 in the first place).
Blog post with videos etc and a lot more info.
