Dupliframes tut question

I’m working through the dupliframes tutorial,


and when I get the link skinned it has a black plane in the middle of it, positioned where a soap bubble film would be if you dipped the link into soapy water. I was expecting it to disappear when I got to the point of:

“When you leave Edit Mode, you can now see the object in a shaded view. But it is very dark. To correct this, enter Edit Mode and select all vertices, then press WKEY”,

but it did not disappear.

The unwanted plane is totally black, and remains whether I use wkey to switch directions or not. What am I doing wrong?


Dunno, maybe select the path curve and switch direction on it.
