Hi, I'm fairly new to ZBrush, 4R4 is my first version.

I'm hoping someone might be able to guide me on the two points below:-

I am trying to work out how to add the Tri-Part Zipper brush to a mesh.

Despite pouring over a load of docs and some tutorial videos at ZBrush Central, I'm still not much wiser about it.

I'm simply trying to get it to snap to my imported mesh tool.

I've got "Curve" on in the "Stroke" menu, with "Bend" and "Snap" enabled.

But it still doesn't seem to reliably snap to my imported mesh tool.

Am I missing a simple step?

My other issue is, if using the Semi-Open Zipper variant, how do I apply the Semi-Open Zipper Bottom part, then release that from edit and add the Top-Left and Top-Right parts?

Many thanks for any help or advice you can offer...
