intersting to looking a 3d mesh point from your project uploaded, but i still did not know how to set point on a node? i try to download the model and import it on blender i thought its from origin but its not, any advice?
Just add a vertex in blender where you want.
@cristo1 's got the idea for the most specific placement, in the test case it just uses one of the vertex points from the node, based on vertex index.
thank guys for the answer appreciate
