I'm using some older neftis hair on a model and every time I click the mouse, it seems to want to redraw every strand of hair, slowing the editing process down (and raising the frustration levels to new heights). I've tried making the hair invisible during editing to no avail and have just settled on saving two versions of my model, 1 w/hair, 1 w/out, and getting everything ready to render using the first and substituting the second at the last minute. But there must be some way to work with hair without these limitations! I just can't figure it out.
