I am not quite sure how that should work with the lattice (I am pretty new to maya and 3d). The lashes don`t just move but have to really deform - I have the deformed lash-objects ready for the blend shapes (and I really don`t want to modell them again - I took me already quite some time).

As I understand the lattice is just something to deform more efficently, and you can animate this deformation - but then you have to deform it every time the character blinks for example. Sounds pretty time-consuming . . .

Is there really no way to make a blend-shape with a group of objects?
