I think I'm doing something wrong, or FR is mocking me... As you can see from the jpg "Store position" I'm storing the initial point position values in a custom attribute ( tmp.origin )
Then I compare ( by setting another ice node in animation mode ) the point position values by getting the self.origin and getting the distance to the point position of the shape point position. Looks like its not working, because I have huge values, while if I try to plug the point position I have proper values ( 0 around the neck area, other values different to zero arounf the mounth ) I also notice that I cannot trigger the shapes from the shape manager, probably because of the lipsync itself, or the envelope or something else...so I'm thinking that FR overrides/reset the shapes ( considering tha absurd values I got ). I also tried to import all the shapes as single meshes and apply an ice tree on them, but if I try to reference a value which is on another mesh it breaks ( some strange error ) At this point I'm thinking to go with the game export and then get all the info from there, but I would like to know if I'm doing something wrong. Also, most important, I have a list of 3d vectors if I compare the points position...even if I plug an array average node I still have 3d vectors...what I have to do to have a single ( average? ) scalar value?
