How to uv map probuilder polyshape mesh ribbons?

Hi all, I'm using ProBuilder to create polyshapes, extrusion of 3 units, then deleting the top/bottom faces to create mesh ribbons. I'm trying to use this texture (1024x256), tiled around the ribbon:



The goal being to create a floating island 'edge'. By default this ends up looking like this:



Using tiling in the shader set to .083 / .333 I end up with this:



Close ... but the texture isn't continuing face-to-face. Using the Probuilder UV editor I can get faces to connect using auto/group selected face OR by using manual / project as planar but in both cases, the texture is inconsistently stretched like so:



ALSO, it's hard to see above but the rendering always seems to include 1px repeat of the texture vertically, zoomed-in view:



So - two questions:

1. Is there a simple set of steps to get probuilder to uv map these ribbons as I'd like them?
2. How can I remove that 1px texture-repeat artifact? Edit - guess I can at least hide this by using a tiny offset in the shader ... would be nice not to have to!

Thanks!

 

So ... I did end up adding an offset to the shader.

For the stretching issue ... the only 'solution' I could find was to select a face then control-click the adjacent (this triggers auto-stitching in probuilder, I guess) ... then repeat all around the mesh ribbon.

Still looking for a way to get PB to do this without the hassle of manually clicking each face!

 

Bump - still looking for a way to either make UV mapping work as expected for mesh ribbons OR a way to auto-stitch every face on a ribbon without manually selecting every face and control-clicking the next.
