Hi!

I would like to create an array containing all the neighbour primitives of each primitive. Is there already a function for that?

…I should clarify why I need this. I was using the Instant Meshes sop and noticed weird polygons. 2 primitives share 3 points with each-other. I tried using polyDoctor and Clean but they don't fix that problem.

That's why I would like to find primitive neighbours so I can group those specific primitives.

depends on what you define as neighbours, but to get polygons that share an edge with the current polygon
i[]@nbrs = polyneighbours(0, @primnum);

Ah nice!

The goal of finding neighbour prims is just to have quicler cook times by avoiding to pass over all prims.

Thanks.
