Closest point in point cloud

Hi!

I have two sets of point clouds, one which is extracted from a building footprint, which all has Z=0, and one which is a laser scan of the roof. I want to find the closest point in XY axis so the footprint point cloud might inherit the Z value of the roof point cloud. I figured I would project the roof cloud to Z=0, and simply take the index of the closest point. However, I am struggling with the Point Cloud Closest Point component. It gives me strange results. I assume I am doing something wrong, but I just can’t figure it out. Any ideas what is happening?

Thank you

Okay, nevermind, I had managed to jumble the tree branches, so nothing corresponded, that’s why!
