Hello, never seen a way to grab an attribute like that in a parameter channel (you probably should use a prim or point expression to lookup the value).

Hello,
There is an 'ignore flat edge' option in the exclusions section of the edge bevel.
For a 10 sections tube, you need to set an angle slightly higher than 360/10.
Depending how you build your geo, there is probably a way to tag those edges upstream in the process, making the process more reliable than based on an angle. (.hip attached)

Beside, as your tree already comes with usable uv's (after a bit of geo cleaning), you might as well use a simple xyz dist to warp a "2d" curves network around your trunk.

Hello,
I'm not really familiar to this "creep" operator (seems kinda old), but according to the doc, the surface need to be a Nurbs geo.
So instead of the polyloft, you might want to copy nurbs circle, and use the skin operator to build a nurbs surface.
From a quick test, it seems to work here about the vines projection .

The geometry of the Source op is crept along the path of the Path op. The path type can be any primitive, but should define a surface (e.g. NURBS surface, primitive tube, etc.)

Salut Olivier,
You first need to find a way to close one side with a curve (the red curve in this example), maybe you will need a bit of vex, like starting from the first valence 1 point, and find the closest next valence 1 point, and build a polyline with those two points. But maybe you can find an easier way to isolate this 2 points, I don`t know the setup.
After that, fuse everything, polypath to create a single ordered curve, and the end sop to close it as polygon.

Hello,
I suppose you first need to collect every point sharing the same position, and apply the test chunk by chunk.
Until someone can dig into your code (not my cup of tea), why don't use the fuse operator ? You can add an additional attribute to snap (N for instance), and use sum as output. Seems to work here :
