MAN9A
I meant, for example, that if I find a $NX in an example's expression, I can go to the “GLOBAL VARIABLES LIST” and find that $NX means the X coordinate of the Point's Normal (I don't know if it's true, that's because I need the List)
See the help of the:
point sop
primative sop
copy sop
there will be a list of usable local variables in there.
if you want to play around with expressions go Alt+Shift+T, this wil open textport.
next type in “exhelp” without the quotes.
you get a list of expresion functions you can use.
if you wanna see the help of that expression go:
for example “exhelp point”
