Hi!

I connected 2 polygonal geos (not curves) to the IntersectionAnalysis sop:

input 0: 428108 primitives
input 1: 24494 primitives

I toggled Input Number and Primitive Number but when I look at the geo Spreadsheet, it says one of the hit from input 0 is primitive number 496294. The problem is I don't even have that many primitives in input 0. How can I get that result?

...is that sop only meant to be used with curves.. ?!

Can't check right now, but I believe intersection analysis expects triangulated geo, and if it's not then it triangulates internally

Therefore the numbers may refer to the triangulated prims

(There is a warning on your node which probably says something along those lines)

So try adding Divide SOP to triangulate before and see if the numbers match

Arg, yes, I forgot to read the warning:

A triangle and curve mesh is required on the input for correct attribute output.A triangle and curve mesh is required on the input for correct attribute output.

I ended up using another method that did not require those attributes.
