So here are the complete steps I used: ⋅ create a large-ish square ⋅ set fill to linear gradient ⋅ apply the "noise transparency" filter ⋅ edit the "noise transparency" filter ⋅ edit turbulence effect parameters ⋅ change...

I found that I can: ⋅ edit the "noise transparency" filter ⋅ edit turbulence effect parameters ⋅ change the type from "fractal noise" to "turbulence" Whereas "fractal noise" gave me non-discrete cloudiness, "turbulence" ...

All, I'm trying to draw something that looks like an interstellar nebula within the confines of an irregular, closed shape. I drew the irregular closed shape, then selected filters->ABCs->noise transparency. It looks plausible inside the shape, but it cuts off sharply at the edges. I could do a simp...
