add points to shape , but not at frame ZERO

[max]

hello, I am italian boy and need help :

my operation for example of animation :


1- drawing a hand with 4 fingers at frame zero

2- move to right ( frame 30 ) the slider and move the hand

3- now I want "make a morphing " , by create a new finger ( the 5°) : at frame 40 I add to hand 5 or 6 new points

4- at frame 60 I have moved the new points for give the finger shape

5- now I try to slide the timeline to frame zero but .... AHHHH !! the
hand- shape is deformed !

can you help me ? why add points not at frame zero is a shape-disaster?

I have made same operation with flash and the result is different !


thank you , ciao ciao Massimiliano

hi max, I am new to moho as well, but I think that moho can tween just between shapes with the same number of points.
That means, position of points can be animated over time, but not the total number. When you add points at frame 100, it will be there at frame 0! The same way AFter Effects works with animating masks, so this is not special for moho.
Flash can make form tweenings between different shapes, but
1) Flash does not care very much about points at all, and
2) Form tweens in Flash very often have unexpected results.

About your hand:
you have to think what you want to do with your hand, adding extra points from the beginning at parts you want to extrude. You can use a scipt in "scripts - draw - split curve" with no effort.
Anyway, a finger that rises from the hand like a little mushroom will look strange, so do it quick, if possible...

I'd just put all the points you need in at frame 0, and just hide them away amongst the lines of your shape until they're needed
