Figured it out! Plug one stream into the first port and one into the second of a wrangle: int match_pt = findattribval(1, "point", "id", @id); removepoint(0, match_pt);

I have two sets of points and I want to compare them by id. If there are matching ids then I want to delete the matched from one of the sets. Any pointers appreciated. Cheers

post your hip file. this is not normal behaviour

I'm building up a crowd for some stadium work - the mocap out of the box might wll do the job but it's only men - anyone know where I can get some women?

Hi, I'm trying to find a way to export nested .ass files - for example with a crowd. I can get a crowd exported using alembics using this method - but I was wondering if anyone could point me in the right direction for exporting, say, each agent as an arnold procedural within a single arnold procedural i.e. nested. cheers

you can create your own - sort of - by writing to disk and then opening the written sequence with another app e.g. rv

Anyone know how to stop CHOPs calculating everytime something upstream changes? Even if I remove it from the stream it halts houdini whilst it calculates.

scratch that attributeOrient does do what I want

A basic question I have some groom attributes on my rest geo, I then scatter based on density and so I want the groom attributes on the newly scattered points. I then attribute interpolate these points across to my animated geo. How do I get the groom attributes to follow across correctly too? I know the attributeOrient SOP does some of the work but not all. Any help appreciated. cheers

If it's just falling snow then points do fine

I'm being a donut. Just setting input A P to input 2 P is doing what I want.......

Thanks Atom, That doesn't quite do what I want - the resulting geo does not match the deformed sim closely enough. This is because there's no useful frame to which I can freeze and make a rest. As I said - Match Toplogy SOP does what I want - it's just seriously slow once I start getting to the number of feathers I want to be matching. cheers

yeah

I've run it through a Carbon Plumage sim, which has changed the prim order.

I have two sets of geo - they have the same geo but the primnumbers have been changed in the second set. The Match Topology SOP does exactly what I want - which is to reorder the first inputs prims based on the second input, but it's very slow on a lot of data. Any clues as to how I can either a) speed it up or b ) build a quicker one? Tried using combinations of attribute copy/transfer and sort SOP but not to any success as yet. cheers
