Point Cloud with attribute filtering Sept. 24, 2015, 5:09 p.m.

So for that i would have to create multiple groups? right? since for every point in the leads group that i loop through, the group needs to be different, for every point, i want to get all other points trails, so all trails BUT the one point i am currently processing..

I was thinking about the looping as well, but i couldn't really figure it out, since in my “point cloud open” node, if i tell it to get 10 points, after this i filter away the points that belong to the “own” trail, and that operation might filter away all the points i fetched from the point cloud open node.
I guess i could remove the count limit, and only fetch points based on proximity, filter away the ones that belong to the correct trails, and then cap to the amount i want, but it doesn't really smell right.
Or maybe I'm just thinking about this all wrong

I would be really interested in how this could be done with point clouds, but for this task i had, since it was in a bit of a hurry, i solved it all through a sop solver instead, which worked all fine.

Most of my Houdini knowledge come from your Vimeo tutorials btw..
Thanks a bunch for all of that fabulous information you put out there.

Point Cloud with attribute filtering Sept. 23, 2015, 5:43 p.m.

Hey, i have a scene with water trails forming which are led by a particle stream named “leads”, these in turn replicate into “trails” with an attribute to which lead they came from.

What i would like to have is that the trails should merge when a lead particle comes close enough to another trail, with a small force, to stick it into place.

My setup is to have a popvop where i read in the points through a “point cloud open”, and the first (minor) problem is that i would like to filter the point cloud so that i only get the trails, and not the leads.
The bigger issue is that when i actually find the points in the point cloud that the leads are close to, it's in most cases it's own trail, so for the point cloud, i would like to filter away the points that have the attribute that points to the current lead.

Are there a better way to solve this? i'm all ears
And, for educational purposes, is there a way to filter the point cloud this way before attracting the lead to the trails?

Target geometry on multiple cloth objects Sept. 15, 2015, 5:42 p.m.

Does anyone know of a way to apply softbodytargetproperties to split cloth objects?

I have a Cloth Object that splits one single object into multiple new objects, so that when i try to use the source object as a target using a softbodytargetproperties the target, and “pin to internal animation” nodes behave weird.

I tried using the primitive group to set using the sphere$OBJID, but i cant seem to get it right
