The point that Steven and I were getting at is that simulations don't need to be cumulative. For example if you plug (0,0,0) into Set PointPosition, it's not going anywhere. So, you might be able to accomplish what you want to do with states.
Another approach that might work is to have multiple point clouds, e.g., one for display and rendering, one for animation, and one for simulation, and then use a Boolean to control whether the display cloud reads its poistion from the animation or simulation cloud. gray From: softimage-boun...@listproc.autodesk.com [mailto:softimage-boun...@listproc.autodesk.com] On Behalf Of Gustavo Eggert Boehs Sent: Friday, June 22, 2012 03:37 PM To: softimage@listproc.autodesk.com Subject: Re: Evalution outside simulation It is simple stuff like transformations, randomizations, sin functions and all that. Problem is I am trying to reproduce the (perceived) "ease of use" from moGraph. In it MOST things happen in a unsimulated envoiroment, as it is a lot faster to work in this fashion. You can work and scrub through the timeline interactivly. But then it allows you to trigger simulation at some point or event, which is nice. I could even try to re-work most of my nodes to have a simulated and unsimulated version, as the cumulative effect of simulation will break most of them, as they are right now. But fact is, it is a goal to be as non-simulated as possible. I understand it is an uncommon request, a bit of overkill really, and people can achieve the effect they want in other ways... I just wanted to double check if there was any undocumented way of doing this. 2012/6/22 Steven Caron <car...@gmail.com<mailto:car...@gmail.com>> also, can you just branch and set point position on those particles instead? s On Fri, Jun 22, 2012 at 11:30 AM, Grahame Fuller <grahame.ful...@autodesk.com<mailto:grahame.ful...@autodesk.com>> wrote: What sort of procedural animation?

The thing you described is at the core of how ice works and there is no way around that as far as I know.

Trying to go further in my efforts of reproducing much of the functionallity found in C4Ds moGraph I´ve hit a wall. The problem is trying to mix procedural animation with simulations. When a pointcloud has a simulation in its stack, as we all know, everything which is underneath this point wont be evaluated. My question is: is it possible to trigger in and out of a state of simulation with a per point boolean? Best regards -- Gustavo E Boehs 3d Artist http://www.gustavoeb.com.br/blog
