Hi
Like the title says I'm trying to match point numbers between geometry with exactly the same topology (however point numbers are in diffrent order which breaks down the animation that I'm working on). I've created and attribute and assigned point numbers of first geo to this attribute, then I've tried to use sort SOP “by attribute” option on the second geometry match the point numbers but it didn't work, the sort node change the numbers a bit but they didn't match. For some reason when I use the attribute transfer node it works for the 10 first frames of the animation and then it breaks down. Attribute copy doesn't work. I attach exaple hip file, hopes this helps to understand what I'm trying to achieve, Any help would be reatly appreciated!

believe it or not there is Match Topology SOP for this purpose
in your case it works without any hint, but you can provide some hint points

Oh wow. That's so simple… I even was trying to do that in Vex but couldn't figure it out. You're a life saver Tomas. Thank you.
