Compound Nodes seem to be unstable and not-quite-ready for reliable use.  I have reported two crash bugs with them.  For the second one, I can't upload the example file they need, so I'm putting it here, where they can find it or others can test to verify the bug.

Change the file extension from ".pzz.txt" back to ".pzz" to use the file.  Open the file, go to the Materials Room, select the Preview material for prop "ball_1".  Attempt to connect the "nipple_mask_compd_2" compound node to the "Blender_9" Blending input. On my system, any effort to connect this compound node to another node crashes Poser. Obviously this is a problem.

My other problem involves a Poser App Crash when creating a second Compound Node on a given material, without first stepping out of that material.  If you leave that material for another, then return, there is no crash.  So that's the workaround: leave the material and return, before creating the next Compound Node.  The Poser Team has verified this bug and is working on it.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
