hi...

wiggle up and down but from a base line floor


I have some vegetables doing a conga samba in 3D and I am trying to get them to wiggle up and down, but also up and down accurately from the floor where they meet the shadow. At the moment they now go through the floor and I cant work out how to stop this. This is what I am using.

w = wiggle(2,50);
[value[0],w[1]]

This expression is used on a null layer for a number of them to do this in time with each other.

Thanks in advance

Thanks for all your help

See if this is close to what you're after:

w = wiggle(1,50)-value;
[value[0],value[1]-Math.abs(w[1])]

Cool Dan !

brilliant..

I would like to use that as well with some of the other characters with audio amplitude, are there any adjustments to be made to this expression and if so how?

please thanks in advance.

Probably. You'll have to be more specific about what you have in mind though.

The part you'll replace is the value of 'w'

You can select that part and pick-whip it to any other value you want.
