  Group settings in TP won't stick the first few times

  Posted by Steve Bentley on September 19, 2021 at 7:02 pm

  I’ve got about 20 Groups of TP’s that I’m swapping back and forth to another set of twenty groups.

  I’ve got a Pass node assigned to Group 1 being tested in an Ag node and then being passed to a PGroup node set to Group 2 (and yes, it’s the right PGroup node – really? they couldn’t come up with a second different name for this one after all this time?). Because of execution order, the swap back is in another expresso tag with a lower priority, but it has the same layout as this. So far so good.

  For the second of twenty sets, I duplicate that cluster of three nodes to make the second of twenty swaps and then point this new trio to the next pair of Groups, then go to the swap back expresso tag and duplicate and switch those trio of Groups settings as well, then run the animation and it doesn’t initially work – with good reason – the group selections haven’t taken!!! (in the duplicated nodes)

  I can go back into to each expresso tag, and sure enough, the duplicate trio is still set to the old set of groups it inherited when I duplicated (control dragged) the trio to use again. Usually when I change the group values again this will stick finally (perhaps it’s the harder, angrier mouse click that does it). But why didn’t it take the first time? Once I’ve set the groups a second time (and sometimes a third time) all works as you would expect, so the node method is sound.

  To set the Groups, I am dragging the Group out of the Group list from the TP settings and placing it on the Group param in the Pass node attribute dialog. Is there a better way? Is there a more definite way? Is this a known thing or a feature of R24? Is there some “cycling” I have to do to make these values permanent?

  I’m not sure but I think if I duplicate the trio in both expresso layouts and then run the animation and THEN change the Group settings it will stick, so it’s something about the animation running that cleanses those group input ports.

  Is there a trick?

  Thanks
