I am trying to get a grip on NE by following some (basic) projects in the Elephant Repository
(9 Oct 2019  (301 of 441) 9476.301  ) using “ProjecMP.nod” from Karsten
I have tried to recreate a post from Pilou:
But it seems I have missed some basics!
Nothing I have tried In and Out Progenitors and setting up a blank Macro to house the ProjectPM node is giving me any result. I cannot even save the setup. See attached images

On the other hand “Helix2Helix.nod” also from Karsten macro runs no problem with no In Out progenitors.
