Cycles - can't intercept with hair info node

[Gregorein]

Hi,
it’s been a long time since I had to post

I’m having problem with cycles after i upgraded to 2.70 but after created a complex hair shader, due to some error it won’t work.
It depends on a setup similar to this, but the effect doesn’t work, as shown.

I believe this should work, what do I do wrong?

If your object has multiple materials check you have assigned the correct one for the Hair

Attach or post a link to your blend file

Seems ok with the line and curve segment primitives, but not with triangles. Was that always the case?

[Gregorein]

Well, that was unexpected - it works for me too.
I have changed to triangles to render faster and I forgot.

Thanks!
