IvyGen only creating small/short results

Hello,

I’ve searched the forum here, and found posts regarding the IvyGen addon, but none specifically addressing the issue I’m having.

For starters, I’m running 2.79a on Linux.

So, I follow the instructions: Create object > Edit Mode > Select Vertex > Snap Cursor to Selected > Object Mode > Add Curve > Add Ivy To Mesh

And the result is always just a small, short stalk. This happens with the default settings, and it happens no matter how I adjust it. From every video I’ve seen, the default options should produce something more representative of actual ivy, and adjustments should be increasing its length and such… Nothing happens to me. No matter what I change, or how much, it stays about the same length, only changing direction slightly… usually going into the object instead of outside it (normals are facing out, in case you’re curious).

So… Is there a known issue with the addon with 2.79a, or am I just having an unusually bad time with it?

Thanks a bunch for the help!
