Hair not quite following the guide. This looks like what happens when transformations haven’t been applied to one of the objects.Translations should be compensated for in the addon but I don’t believe that rotation and scale are. You may need to apply transformations before generating hair.
2)HairNet only works with the guide hair so switching to interpolated mode is controlled by Blender itself. I don’t know what could be causing a change of direction there. Does reversing the direction of the curve object make a difference?
It looks like applying the transformations worked! I also experimented and figured out that It was easier to add children hairs in simple mode and then change those settings.
Although, I’m curious, is there a way I can have the hair return to its original position in a hair dynamics simulation?
