I try to use the hair system to do grass and like to animate it with a vortex. When hair dynamics is'nt active, the force fields actually affect the hair/grass but its not animated.

But when I activate the dynamics, it stop being affected by anything, and its not even moving with the gravity.

I read some tutorial and docs and I can't see what I'm missing.

I don't know if this is important but I'm using the bahiagrass pack from blender guru. I tried to move about anything in the hair parameters without succes I can provide screenshot if needed but since I don't really know what could be important here.

  • $\begingroup$ have you baked the hair's dynamics? press ctrl+a and see if the hair start being affected by the vortex $\endgroup$ – user2816 Jun 3 '16 at 16:15
  • $\begingroup$ I tried ctrl+a and also bake from the cache section but it doesn't do anything more $\endgroup$ – eephyne Jun 3 '16 at 16:36
  • $\begingroup$ can you upload some screenshots of the settings of the particle system? and maybe the vertex settings too. $\endgroup$ – user2816 Jun 3 '16 at 16:42
  • $\begingroup$ here the particle settings, sorry for the raw screenshot, I'm mouseless and painfully do thing with trackpad >>. imgur.com/a/HIeQe . the circles you see on the scene is the wind force field (I was testing with wind right now) $\endgroup$ – eephyne Jun 3 '16 at 17:01
  • $\begingroup$ Well. I started over and it work very well now (except that the vortex is'nt acting like I thought it was and the failoff is not really working (at least like I wanted) But I'll ask another question for that. Since I don't have an answer I don't really know what to do for this one: Vote for delete ? post an answer saying to do it again (I don't think that a good idea) ? $\endgroup$ – eephyne Jun 5 '16 at 5:51
