Hi gang,

I have to export the alpha channel of my comp, nothing really fancy at
first, but then I noticed that my semi-transparent extruded shape objects
are considered opaque.

You can see here on my screenshot:
https://www.dropbox.com/s/1f4u9v85d54sw7w/transparency.png The selected
object is 45% opaque, and I should somehow see the checkboard through it,
but no, the transparency is filled with some default black environment.

At first I thought it was because my difraction was at 1.5 but no matter
what value I change, it's always looking opaque when I put it against a
transparent background (when I put an object behind it behaves correctly,
it's only when the bg is transparent.

Any idea how to circumvent this ? Is it intended behavior ? (i'm quite new
to Raytracing)

Thanks !

Cheers,

Seb
