Hi all,
i know my noob brain is to blame here…. I'm using the creep sop to flow some points over a surface which works well, until i want to edit the base mesh with polysplit. Without polysplit the convert node to turn polymesh into nurbs surface says I have 1 nurbs surface as I would expect, but adding an edgeloop i now get 90 individual nurbs surfaces and my flowing points are understandably only flowing in the first one. I don't fully understand geometry in houdini as it's so different to other software and I imagine this is part of the problem. I've tried a shed load of convert options, nurbs nodes, remesh, sort… the list goes on but no dice.
Any clues?
Using 17.0.059 Win7
cheers,
Andi.
Uploaded a simple hip just in case…

The polysplit leaves the mesh in a disorderly state.
Shifting the vertices (reverse sop) so that they are all wound starting at the same corner allows the convert to grok the polys as a mesh again.
Enabling vertex number display in the scene viewer will illustrate this better.
The shared vertices should all look like this:
3 0
2 1
