I went through all of the plugins I felt were worth downloading. I made an index of every effect in them. Now when I do a tutorial, I can search for the required effect and find out what plug in I need, and hopefully, where to find in the PDN UI.
So it looks like I have 3 options for outline. Two from effect -> object, and one in effect -> stylize. None of them have an option to do an interior outline as called for in the tutorial.
I believe what I have to do is sligtly srink a copy of the original, larger object, and outline that. Afterwards, i need to clear out the center turning it into alpha transparency.
But the tutorial makes me believe there is a more efficient way to do this. I just can't find it.
