Maya extrude spline UV mapping problem

pr1970

Hi All

I`ve always had issues with Maya`s extrude surface option and uv mapping, I can never get it to perform a good UV map from the off.

In the screenshot attached, i have a linear spline (cross-section) with how I want the uv`s fit to, and then i`ve extruded along a curve with a U:1 and V:13 . And I expect the uv`s should map correctly, but regardless of the U/V Type they never do.

It always involves tweeking it with unfold uvs. Its a similar problem across all the surface creation options in Maya.

Any ideas?

Thanks

Select the most left vertical row of UV's,then In the uv Editor,go Polygons-->Unfold-->Optionbox,then be sure to tick PinUV's(pin selected),and in this case use a vertival constraint,then hit Apply.Have a fiddle with it basically.

The UV creation for NURBS operations pretty much does what you see there, ie: normalizing the UVs into 0-1.

I do basically what St. Sabbath is talking about, unwrap vertical, then horizontal, make the left and right edge straight, then use a script to align all the corresponding uvs.

It sucks that it doesn't set things up proportionally from the get go, but it is a fairly quick fix.

ok thanks, yeah it does suck it doesnt do it from the when it builds the object.

What script are you talking about for aligning?

I use a suite of scripts called Ninja Dojo, which isn't free, but has a script for straightening UVs (which is what I meant to say in the first place).

I believe nightshade UV editor also has a function like this, and it is free.

As does UV deluxe (also free).

Ya UV deluxe and nightshade UV editor got great tools I won't even think of doing uvs in Maya with out one of these tools.
