Cycles - Glass without reflectivity or Transparent with refraction?

The glass BSDF has two main methods. Reflection and refraction.
The transparent BSDF has neither.

The question is, is it yet possible to make a gas-like material that has only refraction but no reflection?

It seems I can’t find out if it’s possible.
I’ve also no idea yet how to use Fresnel properly yet.

I´d be happy for every enlightment, else I got to ditch cycles for my current project and use Luxrender, which I don’t really want.

Concerning the use for Fresnel, so far the only way I have found is by connecting it to the factor of a mix shader. I haven’t had the time to experiment with it yet, so that’s as much as I can tell you, sorry. :frowning:

The glass shader in Cycles is by default non-reflective, isn’t it?

Ha, beat me out of town with a stick - you’re right.

Haha! Good to know I’m not entirely crazy then! :smiley:

Glass shader has reflections now. =[
