In Blender, if you hit M key and select Merge At Center, all the selected points will be merged into 1 point.
I want to ask how should I perform the same action in Houdini?
I research a lot and discovered that some people recommend using the Fuse Node, but I still cannot figure out what setting in the Fuse Node should it take to merge all points at center.
Got the solution.
Use an ExtractCentroid Node, and set the Run Over option to Detail.
