Yes!

The index for refraction is 1.52.

The filmindex is ignored since there is no filmwidth.

you also need to set the reflection higher...
both reflection and transmission should be 0.9 or so...

That depends on how much transparent do you want the glass to be.
The more the transmission values are high the more the glass is transparent (and of course less coloured).

Hi!
I just realized that Octane can't project colored light that's been filtered by colored glass when using the daylight environment.
In an architectural scene where I'm using colorful stripes of glass, the daylight that passes through that glass should be projected on the objects behind with the specific color of the glass that acts like a filter retaining all the wave lengths of the white light but the one corresponding to the filter's color. Well, the rendering engine apparently can't do that.
The rendering attached was made with a different software.

yeap use an HDRI, since sun doesn't go thru transparent materials yet, for it to work there is an small workaround, lowering the glass opacity to use along with the sun system.
