One way colliders?

I remember seeing a preview video on unity 4.6 featuring one way colliders. Is this available in the current beta build?
I could mess around with layers but a proper solution would obviously be preferred.
Thanks!

Hi, this wasn’t colliders but a setting on the ‘GraphicsRaycaster’ to ignore backfacing graphics. This is available in 4.6.

It seems like I was mistaken with unity5;

Thanks for the reply :slight_smile:
