I can see you will be an asset to the forums so I welcome you.
I am a fellow Poser user, in conjunction with C3D. and Anime Studio.
Any enlightenment into using UV stepper would be useful.
Thanks.
Thanks for the "welcome," uncle808us! I've been here since 2014, but I don't post that often (so I guess that's why it still says "New member" under my username?)
I use UV Stepper most often to scale and center UVs on the "stage" (as the script calls it), but I also make frequent use of invert u and invert v as well as point alignment h and v (which automatically scales all selected points to a horizontal or vertical line, faster and more precisely than doing it with the gadget tool).
I find it pretty easy to UV map props in Cheetah, but I'm still trying to figure out the best way to map clothing items, and in the process I've experimented with UV Stepper's Weld UV option. What it does is let you "rejoin" vertices that might've gotten separated in the process of unwrapping the mesh, esp. if you used seams. The verts are single items on the mesh, but in the UV space they can end up in two locations, which you've probably seen if you've ever selected a vertex on a mesh and noticed that two vertices seem to be selected on the UV space. It's an inevitable result of unwrapping a mesh, but sometimes you want to "reunite" a set of verts in order to make texturing easier, like the top or edge seams on a shirt. So I use the Weld UV option to "reunite" those verts and then pin them before doing any further unwrapping.
I haven't yet explored the other options in UV Stepper, but I'm sure I will eventually! If there's a specific issue you're trying to figure out, let me know, and if it's something I've figured out, I'll share what I learned!
