Hello, I'm trying to make an OTL that basically creates a spline IK system, and make it so that you can specify how many joints to use in your joint system, via an attribute on the OTL. I thought this would've been the kind of thing Houdini excels at, but I've been having a hard time finding examples of creating X number of objects. And I can't seem to use for loops in the context I create joints, so that seems to not be an option. I'm starting to think that I need to use a Python node, but I'm not sure that it can be triggered via updates to the OTL attribute, like I would do with PyQt. But I couldn't find many examples or references for creating joints via Python in Houdini. Would anyone be able to help me out, or point me to some relevant examples of creating N number of objects procedurally? Thanks!

python is the answer here…

attached is a shelf tool that mimics the Bones From Curve tool

Cool, thanks so much! I'm still new at this, but I'll try figuring a way to get something like that into a Python node.
