It's been awhile for me but I believe you can use a per-particle age attribute, (agePP maybe?) to check the age of the particle in your expression.
>From there you can do a few things to apply the force. You could manually read/add the force inside the runtime expression rather than connecting the force. You could simply add velocity purely in the expression (ease of this depends on the force you want to emulate). Or Maya also has this somewhat dirty feature where if you give the particle a PP attribute with the correct name it will allow you to control field magnitude inside the expression on a PP basis: https://knowledge.autodesk.com/support/maya/learn-explore/caas/CloudHelp/cloudhelp/2017/ENU/Maya/files/GUID-CFEFD7A0-0236-4CE9-8C71-B7A94C7C1E7D-htm.html On Tue, Dec 6, 2016 at 9:08 AM, Ben Beckett <nebbeck...@gmail.com> wrote: > I would love to do it in ice but if I leave no one can fix it, not that > any one can use Maya particles there any way! > > On 6 December 2016 at 13:17, Rob Wuijster <r...@casema.nl> wrote: > >> Just do it in ICE, and forget about the Maya legacy stuff.
