I'm going to figure that you created layer 2 at frame 3, and that may be the problem. Creating new layers inside Switchlayers at other than frame zero is kind of a special case that's mostly been used for importing frame-by-frame (traditional) type animation. Since your new layer effectively doesn't even exist until frame 3, I think the Onion Skinning is interpreting that as nothing does yet. Maybe a glitch, I don't usually use that technique myself, but a good general rule is, unless you have a very specific reason to do otherwise, create all your new layers at frame zero.
I'll give that a try--- though the tut definately is telling me to make the new layer at frame 3 (or is it telling me to keyframe it there?) --a matter of interpretation perhaps... I'll try it your way and see...
Im wondering,
Did you select the 1st layer on frame 1 (by right clicking on swtich layer and choosing layer one), making an onion skin on that frame (nice little blue box appears on the timeline), then on frame 3, doing the same but selecting layer 2?
When you select a layer by right clicking on the switch layer, it should make a keyframe automatically
sorry my description is crap..i just got home..tired
I thought that neither were external scripts, but perhaps thats the problem. Dunno, I would figure that if extra scripts were unavailable, they just were. Not that they would non-transparently deny you access. Curious.
