I made a hairstyle using ornatrix but when reopening the file the guide spline direction was broken. I turned on and off the Stack and tried various things but could not recover.
thanks for your reply. I'm not using the map and I haven't changed anything, but the spline orientation is wrong when I reopen it. and I opened it immediately after saving it, but it was broken as well. So I'm export spline by CurvesFromStrands and then use GroundStrands everytime...
