Hi everyone,
Im trying to reproduce something I made in blender using geometry nodes because I need to implement it in unreal.
I'm at a point where I'm stuck because I can't find a way to reproduce the behaviour of a node from blender which is the Geometry Proximity node. What that node does is that it has a position input for the geometry I'm using and a geometry input for the target geometry and it computes the closest location on the target geo so I can use it to randomly add branches on walls for example.

Thanks in advance !

Here is a video of what the tool does:

Hi,

You can use point cloud look ups for this in VEX as code or VOPs as nodes. I made a Proximity SOP long ago as a high-level node that does these without having to use point clouds directly.

Higher level Ray SOP
or
Low level xyzdist() VEX function or VOP

Can both find closest location on a surface based on position
