AttributeAffects is just a reference?

hi,all.

I just do an experiment to look how AttributeAffects setting have effect on an compound output. I have a computnd output called "outputFloatComp" that contain 3 child "outputFloatChildA\B\C". when just set AttributeAffects like this:

stat = attributeAffects(inputFloat2, outputFloatChildA);
stat = attributeAffects(inputFloat2, outputFloatChildB);
stat = attributeAffects(inputFloat2, outputFloatChildC);

Or just

stat = attributeAffects(inputFloat2, outputFloatComp);

even only set one child

stat = attributeAffects(inputFloat2, outputFloatChildA);

all works well when i monitor the dirty propagation all child and parent plug are in correct dirty state. This make me a liitle confuse with the effect about AttributeAffects, is this setting just a suggestion for node rather than an absolute rule ?

No its not areference.

Ahh see compounds are all of them so if you set something in the compound they all become dirty.

is this setting just a suggestion for node rather than an absolute rule ?

its a rule, maya compounds are just handled differently than you think thats all. Compounds are not as far as maya is concerned separate things its one thing, any part is the whole thing. I think this may be uinitentional by the way.

So yes to anwer your question compounds dont allways work like one would expect. In this case you changed it so the whole damn thing is dirty. (compounds are mant for things that get updated in one go together so they would all get done in one go)
