its cool i got it working now :) was selecting a single strip of poly's didn't realize you had to select the whole area. works well on simple strips, doesn't work well with... anything else :(
There is an amazing Modo tool where you select an edge and it does a an unfold, like in softimage, but neat and tidy. thanks for the help Pete your a credit to this list :) On 18 December 2013 11:46, <[email protected]> wrote: > contour stretch interprets the geometry as if it were a grid (with a U > and V direction) – likely deformed in space > walking the mesh lets you drive the layout by indicating the four corners > of this grid. > it works on the whole geometry at once – not on a single strip and the > rest by extrapolation. > > in order for this to work it has to find the borders of the object – in > case of a tube you have to open it (select an edge loop and disconnect it) > – for a donut you’ll have to open it in both directions > if the road (a flat ribbon) is circular you’ll have to disconnect an edge > loop as well. > > in the texture select the samples on an existing projection, click on > walking the mesh, and in the viewport click the 4 points in the proper > order (which can be difficult with complex forms) and then right click to > end – then it should give you a rectangular UV layout. > > if the object is very twisted, or deviates a lot from the organised grid > topology (forks in the road for instance) – it might fail or just give > useless results. a long and winding road (pun intended) should work – but a > labyrinthine road won’t – or would need to be approached one path at a time. > also – it usually requires a serious workover to minimize distortions. > > (if you want you can mail me a geometry and I can have a go) > > > > *From:* Sebastien Sterling <[email protected]> > *Sent:* Wednesday, December 18, 2013 10:55 AM > *To:* [email protected] > *Subject:* Re: Old Tool UV strip projection ? > > I think it is the contour stretch UV's, but it doesn't seem to be > working very well, i make my selection and add the projection but it > doesn't tile it as you would expect along the other faces, they are all > weird, am i missing a step ?. > > Yes peter, there is a Walking the mesh function in the Stretch contour > UV's menu, however none of the options seem to do much, :(. > > anyone else use this recently ? > > > On 18 December 2013 10:45, <[email protected]> wrote: > >> I don’t remember the one you describe, but there was a gator-like >> tool, that would create UVs on a polymesh from a nearby nurbs surface. >> shouldn’t be too hard to replicate in XSI: extract an edge loop, create >> an extrusion (nurbs) and gator the UVs from the extrusion to the poly road. >> >> in XSI there is “walking the mesh” in the texture editor, which should be >> fine for a road – without the need to go through a nurbs object. when it >> works, its pretty cool. >> >> >> >> *From:* Sebastien Sterling <[email protected]> >> *Sent:* Wednesday, December 18, 2013 10:15 AM >> *To:* [email protected] >> *Subject:* Old Tool UV strip projection ? >> >> Hello list >> >> Recently i was approached by some maya people looking for an old tool in >> softimage (GASP!) >> >> They want to create uv's for a road, and they think there is some kind of >> tool in softimage, where if you create a projection for a strip of polygons >> on the road, there >> is some kind of automated function using the u and v coordinates which >> automatically finds the rest of the uv's. >> >> This would have been an old tool, ring any bells ? >> > >
