MEL is a scripting language which can embody "open architecture" of maya. By using MEL, user can control maya functions directly/indirectly. Even maya`s GUI (graphic user interface) can be controlled by MEL. Therefore user can add new functions that maya doesn`t have OR customize GUI as their needs. Expression controls attribute of object. User can control an animation which cannot be key framed (e,g. particle). Using expression is similar to script MEL. We will mainly learn how to work with Expression. 1) MEL and Expression 1.2) Differences between MEL and Expression. MEL MEL is more likely completely independent programme. MEL needs complete structure of grammar. MEL is executed no matter animation is played or not. MEL is saved separately with the scene. MEL access to the attribute indirectly. Expression Expression is a correlation with objects. Expression needs only the least rules. Expression is executed only while animation playing. Expression is saved as a part of the scene. Expression access to the attribute directly. ... - tailieumienphi.vn
