I guess I would just have faked it in Mtlx by increasing the specular amount to insanity. But we all know 1 is the max amount, also increasing the color value way above 1 doesn't help either.

Anybody succeeded in replicating something like a cateye reflector, or the reflective material on a warning vest?

Any tips are highly appreciated.

Did you ever find any helpful tips?

I personally got some success by skewing the geometry's normal toward the incoming ray.
