Hi,
there's a curve on the geometry, i need the curve split this geometry.
i only found the "polysplit" looks usefull, but it must split mulally.

any good idears?

and if use the polysplit sop,i need find out every prims' uv nearst to the curve's points, don't know how to find out it yet.

This gentleman has come up with what you're after, you might want to ask him some questions.

You can do that sort of thing with a cookie sop, you just need to turn line into a ribbon first.

I think the issue with the cookie SOP is that it can be a bit unpredictable at times. This seems like a sensible alternative

if you look carefully when he separates all the pieces this has too. I think he must have used the cookie sop inside his otl as driving the polysplit sop from a curve isn't possible, unless it has drastically been changed in H12, I've not had time to check.

It would be brilliant if we can now drive the polysplit sop itself from a curve. I wrote an hdk sop to do that many moons ago because of exactly that limitation. If that has change that would be amazing. Never understood why 95% of sops are procedural but a handful are not.

The Polysplit has changed dramatically.

The PolySplit SOP now allows you to create intermediate points on polygon faces and you no longer are restricted from placing intermediate points on polygon edges but anywhere on the polygon face. This allows you to define a few edge points on or off edges and generate a new split edge that will cut all intermediate polygon edges respecting the drawn split curve shape.

I believe there is a new asset using the added nomenclature in the Polysplit field taking advantage of this new feature.

Jeff, by this statement do you mean that there is a new digital asset in Houdini that does kinda of what we see in the video post above? This is something that would be pretty useful to have in MANY cases
