1. ## Reverse point order only for point group

This is an intriguing problem. I come from grasshopper background and I must say Houdini is one beautiful software. This is a trivial thing to do in grasshopper but I cant seem to find any ways to do it efficiently in Houdini. Maybe I am not understand something fundamental here. I have a grid of points, 10x10, I need the point order to loop from edge to edge. Basically reverse pt order of 10 points every 20 points so it has a looping movement. I tried two approaches looking for an efficient way to achieve this. Copy to points is the worst way for this instance. Red is the attempt which didn't quite work, and Green is the needed outcome done manually. Pt_order_mess.hipnc Anyone have some ideas how I could go about this?
2. ## for each named primitive_problem

i am trying to run over named primitives, but the for each loop seems to pick randomly for each iteration which batch to process. i want the loop to respect the sorted primitives and run over each named primitive as it is in the geometry spreadsheet. How does it pick the first batch for iteration number 0? can i change that? image 1 is before the loop,sorted primitives image 2 is inside the loop with a single pass to see iteration 0 As you can see the first batch the loop chooses to process is not the first batch as sorted before. First batch should be the one named color_229_229_0
3. ## Radial sort of points on a plane

I sometimes need to sort a bunch of points radially. The points lie on a single plane and form a string-like, closed, irregular shape, kind of like a map of a country. I created my own OTL which computes a signed angle between each point and the centroid of the figure, then sorts the points. It works fine, but I was wondering if there's a quick (i.e. just a few SOPs) way to to do this using standard Houdini SOPs.
4. ## Skin & Sort challenge/issue

Hi folks, I face a challenge to setup my underlying curves to skin my in the correct way. The biggest issue I have is to sort all the points in the correct order - I think to do this via a helper curve should do the trick, but I can't find the solution So any help would be appreciated!!! The end result should look like a stadium roof... Thanks so much! Cheers Dominik
5. ## Create a line from randomly numbered points

Hi All! I want to create a line from some randomly numbered points (see pic.) In order to use the Add sop the numbering must be ordered by proximity. Sort by Spatial Proximity does not work good! The numbering that it gives is ok at some areas and messed up in others. I cant use the Match topology sop because there isn't any geo I can use for that. So I guess I have to find an alternative way to do it. Any ideas? Thanks!
6. ## increment every 20th frame in a sort

I have a sort node set to shift. I want to increment offset by 1 every 20th frame. \$F%20==0 sets the offset from 0 to 1 every 20th frame. But how can I increment the value instead of setting to 0 or 1? Thanks.
7. ## Sorting alphabetically in take list

Hi, dows someone know how to sort takes in the take list alphabetically after creation ? Or should I report a feature request? Cheers Dominik
