I digged into particle systems recently, yet i did not have much time (nor i do not have at this moment if i want to finish my work in time) to figure out how does the positioning/rotation exactly work.
I’d like petals to grow from inner calyx ring to exact direction based on its position i just did not figure how to set up origin point (particle object is just subdivided plane) and particle settings to get wanted results.
I attached an image for better imagination of my problem.
Is there any reason why you want to accomplish this by an particle system? For me it more looks like a job for animatibg by shape keys. But then I dont know how exactly you want the animation to look might be anything from very easy to fairly complex.
This one is more of the very easy and sluggish kind but you should get the concept here. petals.blend (615 KB)
It was not correct to say that i want these petals to grow, i just want them to be there and i wanted an ability to change the shape of flower even after all these leaves and petals are added (just change the shape of stem and let the blender do the rest).
I’m going to use these flowers (quite alot of them) as a background for an architectural render.
Just using three paths to make the petal-like parts, and that one path in the background for the profile shape. Using Alt-s or Ctrl-T to pinch or twist at the control points. The active spline settings in the sidebar also have some role in the transition between points, so give those settings a try as well.
Also particles might not be entirely ruled out, as I suppose it’d be possible to have a particle system spawn path objects onto another mesh. However that’d be a bit of a challenge to figure out.
