i want to create a simple graph, which should read the xforms of i.e. 4 ctrl joints and export n-samples from the spline interpolate to array node into a parms dictonary for further use in sops. How can I import geometry and work with that? I only find examples in the graph documentation, where geometry is directly used in the graph like a box or something that will be changed by the parms input paramteres, but nothing about importing premade geo or skeletons. Any ideas?
