    Question ABF correction / "magical" procedures? / academic question

    UV mapping seems to be the Hawt Tawpic.... so here's an academic question:

    The original object was a straight "box", then tortured with Twist and Bend. The UV map is an untouched, raw ABF mapping. (Pretty good!)

    Obviously, to get the UV back to a "straight" representation, one could just get a coffee, buckle down, and start moving points, but for those who are conversant w/the UV tools: Is there any better* way to regularize the UV map?

    *besides going back in time and approaching the problem correctly. It's an academic question.

    If you start with a box I suggest you UV map it before you deform it then it will stay straight.

    Read the footnote.

    Ok, missed that. But sometimes it can be easier to start over and make it the right way instead of trying to fix it afterwards. Your example model seems like a very easy model to just redo.

    Yeah, but it's just an example I whipped up to illustrate the point. For a REAL object, with complicated curves, some method (apparently PX UV Creeper, until it's not available/compatible) would be good for users.

    It's pretty gratifying, to me at least, what a good job ABF actually does.

    Just thought I'd post these as a consideration:

    Literally took ~ 4 clicks not counting the export settings. Didn't even have to select edges as they were already cut in this model. Just Unfolded, Packed and then used the Straighten options.

    Didn' t even have time for the microwave to reheat a mug.

    Rizome, ehhh? ::rubs chin::

    Pretty flippin' magical. --- Are there options for maintaining a correspondence between polygon area and the resulting UV area? Or is this a byproduct of the Straighten option?

    This is not magical it’s what most decent 3d apps can do native or with some plugins. It’s just a proof of LW lack of UV tools.

    You have SO much control. Island groupings. Locking options. Individual island packing preferences. A lot of "I didn't know you could do that with UV's."

    The Unfold 3D vids are the beta of RizomUV. But you'll probably find this one of particular interest:

    Take note at the 3 min. mark of feature found in the menus & not in the UI.

    But also in case you haven't seen them:

    Not needed to use RizomUV, but nice to know the tools are there.
