Which effect? The facial expressions of the primate? Moving around polygons is usually accomplished with the help of deformers. Scripting may be used to set up the deformers, but is not required.

no. not the expressions. the effect of of the whole face being built with individual polygons

Build the entire face then delete anyfaces, then find the delete node and animate the selection membership with a expression like this.

setAttr deleteComponent1.deleteComponents -type componentList 1 ("f["+frame+":999999]")

Please note this is a bit bad in form but it works and ita the anoly sane way for a normal iuser whos not villing to amke a node to do the same thing. Dont relly on this trick over in subsequent referenced/imported files you may get a catasthropic failure. If you want to affect the speed connect a custom time node into the expression and animate its time.

PS: not many maya users would actually know you can do this.

PPS: the video didnt go into the most important bit about polygons (well tahts to be expected it would leave so sour a taste to most watchers that youd cry).

@jooja
you mean i should create the objec that i want and then delete the faces in the order/reverse order that i want them to be animated? where can I find the delete node? please excuse if the questionsseem silly. I am new at this

thanks

[joojaa]

Just delete any face the oder of face creation will be the order in wich they are indexed (you can reseed indexing by merging all into one face). Theres just one deletion.

where can I find the delete node?

hypergraph, attribute editor or the channelbox.

Anyway most people think this is something only houdini can do. because theres no GUI in maya for this.
