Scale object inside subnetwork Aug. 3, 2026, 7:29 a.m.
winkel
F.e. I have one part that is 10 x 10 x 10 and I need the node info of the SOP inside the OBJ inside the subnetwork, to show me f.e. 4 x 4 x 4.
Can you elaborate ?
What is the end goal
Ideas for a non intrusive gradient descent optimizer July 16, 2026, 6:02 p.m.
Say you have some nodes in a subnet, and a target geometry
Without doing any modifications to the subnet, i.e non intrusively, how can you get a set of values for each parameter of each node in the subnet, or of only a subset of the parameters / nodes, that minimizes the distance to the target.
Does it sound like a good task for APEX, Attributes from Parameters, Invoke Compiled Graph, and a bit of metaprogramming to handle the computation graph from AFP ?

Setup for invoking an Attribute From Parameters graph ? June 19, 2026, 12:50 p.m.
I can't get the exact setup to do this:
subnet1 -> some process on a geometry, with no actual geometry inside the subnet, say one subdivide
geo1 -> the actual geometry to process with subnet1
attribute From Parameters for each of those nodes; possibly wired as inputs instead of being referenced in node path, but I believe `opinputpath(".",0)` can take care of this
Then I need to feed wire the two attributeFromParameters to Invoke Compiled Graph
I keep on reading the doc for this node, and it should work in theory, but I can't get a working setup to have a clean separation between process (subnet1) and data (geo1)
My goal is to do something on the graph representation of subnet1 when it's just text after, attribute From Parameters. For example, I would go through some specific values of known verbs and tweak them in a loop.
