So far I've been able to understand a few variables that can be used in expressions:

$F = Frame Number
$PT = Point Number
$T = Time (?)

$X = X position (?)
$Y = X-position (?)
$Z = X-position (?)


As you can see I'm guessing on some of these because I can't seem to find a full list of these in the online docs.

Can some kind soul post a full list or at least point me to where I can find them?

Heya Greg,

I agree. The ‘globals’ should be stored in one convenient place, and they may very well might be, but I have no idea where.

In the meantime, take a look at the help cards for the point sop and copy sop (under the “local variables” anchor), it contains some most-usefull ones.

To further complicate the issue, not all of them are available in all sops.
