Subject : Re: Need a special kind of drag...
Any tips? anyone? At the moment I've made a kind of dynamically deforming filter-like obstacle (a lattice like structure to guide the bubbles) and turned the interframe calculations up to 20 and things are getting sloooooow......

On a side note, the help information on Collision Accuracy reads like this:

Collision Accuracy
Iterations The number of times a particle's position is calculated per interval.
Interframes The number of times a particle's position is calculated per frame.


could somebody please define 'interval' for me? Does this roughly translate as the number of times the position is calculated for each interframe? i.e. are these values complimentary or are they independant of each other?

Cheers,

Dan.

I have a glass of fizzy liquid, now I don't seem to be able to find a way to make the bubbles move with the fluid as if they were aware that they were suspended in a fluid. To clarify, the glass is animated and is jumping around and I need the effect of an iherited velocity for particles *after* they are emitted. I had thought that a drag force parented into the rig might do it but I seems to be a global phenomonen.

I'm testing this with quite fast motions BTW if that helps.

Any ideas most appreciated.... thanks,

DAN
