I have an ecosystem of Primroses, about 14,000, that I'd like to start off being bent over then rise up to normal like they are coming to life but not sure how to do that.

Can I use a function node somewhere for that?
I suppose I could render out some sequences then populate them as billboards.

Right now I'm just populating on a duplicate terrain and animating that height so
the flowers rise up vertcally but that's not as good as having them bend up into position.

I also tried converting the instances to objects, selecting all and trying to animate that way but my Ram gives out before I can complete the task.

If it's already been covered maybe someone could point me to a link.

Just some general ideas should help.
I'm using v6.5.
Thanks.
