So, apparently hair physics is the weakest point of blender. Hair wont collide with objects properly except in miracle cases. Hair wont collide with itself. Hair kinda can move in dynamic fashion but hair sim volume settings will make you to bang your head to wall. Whats the point having and updating the solver with volume algorithms if its not finished? And even if you decide to do hair in other software and then import hair curves to blender - Bang! you cant render those unless converting to geometry which kills the render, the hair shader and ability to use any texture.
Is there any proper workflow for blender dynamic hair? Or we just supposed to use it in still frame renders and 1970s static hairstyles?
