Invoke graph a Subnetwork with a Parallel for Compile Block 2026年10月12日6:02

Is it possible to create a graph from this subnetwork, using Attribute From Parameters SOP, then invoke it, using the multithreaded execution ?

I can only get the result of the last iteration when doing a repeated rotation of the input N times, using By Count/ Merge

For the invocation setup, I group the Compile_begin and Compile_end nodes in begin / end, or even just the foreach_begin / foreach_end in a subnetwork that doesn't even include the Compiled Block around the for_each block

The reason I want to indirectly call the subnetwork, is that I wanted to experiment with meta programming on the output of Attribute From Parameters, try and optimize some meta parameters. The output being basically a program in text form, even a proper graph, the end goal would be to add some code in between and modify the code. But I'm not there yet as I can't really call a simple program that contains a loop. Any thoughts ? Should I skip this and go to APEX or something else ?

Scale object inside subnetwork 2026年8月3日7:29

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 ?

Ideas for a non intrusive gradient descent optimizer 2026年7月16日18:02

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 ?
