I won't describe exactly how I did this because it might be taking away from the tutorial. But I came up on this accidental webbing reaction the other day. This is gaia under a silvered reaction. Amber may explain how this happened to me in her tutorial.
I suspect I know how she did it, because it happened to me on an accident. Hopefully you'll see how Amber's tut can send you off into other directions.
At the time of this posting, I had not read her tutorial yet. But looking at it, yes. This is how I got that transparent look. FWIW: it's dichro under Gaia, under Amber's tutorial (sort of).
