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.
