Expresso attach object to vertex with expresso - object lags in animation


#1

Trying to attach an object to a vertex using xpresso which is working - but the target mesh is being deformed with a pose morph - and the object has a slight lag as the morph moves that vertex around.

guessing it might be a priority or hierarchy issue - any tips?


#2

Change Priority in the Base Tab of the Tag ?

Reading the Help on that section decifers the ordering hence the naiming is not clear.

  • Initial
  • Animation
  • Expresion
  • Dynamics 11.5
  • Genrators

Post an image of your Object Manager it might be an obvious priority issue that can be solved with minor rearrangements.

I don’t understand why this priority nightmare system still exists. You would’ve thought the core rewrite would’ve consigned it to history.


#4

here is my OM in case it offers a clue. I have rearranged the hierarchy stacking order in many ways with no change, and also tried different priority settings and values (though I don’t understand that stuff at all so just guessing). Can’t upload actual file due to NDA issues.

Thanks for any thoughts.


#5

What if you move the xpression tag from the “xpresso” null to the “top hub” null?


#6

thanks for the suggestion - but no change if I do that.

got it - I needed to set the xpresso tag priority to “generators”

Glad you got it sorted.
