Expression for a random point selection over time

[afx]

Basically I have a group of points with something like this as its point selection (4, 5 ,6 12, 16, 20) I want to randomly pick one of these point numbers and over time pick another one of these numbers.

example.

frame (1) = point selection (5)

frame (2) = point selection (12)

frame (3) = point selection (4).......

its getting late, and in zombie mode if I dont make sense I can clarify

$PT == int(rand($F) * $NPT)

?

Looks like that doesn't seem to do the trick

Let me know if you guys think I should be doing this differently

I have a Box node

I then selected a group of points and asigned them to a group node

I now want to individually select one of these points in the group node and translate it, but I over time want to change this selection so that the translation moves from point to point within my selection group

I might be setting this up wrong any suggestions??

If this is really what you want then it might be easy or hard to find a solution depending on what you plan.

After reading it again it sounds like you want:

Have a selection of point on your box

Apply a montainSOP to this group

Or: Add a custom pointSOP expression or even VOPSOP to this group

You can also us the combine tab of the groupSOP to create a subset of your first group.

yea mountain seem to do the quick and drity trick, but it looks like I have to jump into a VOP SOP to get the control I want
