Working with Hair Tool in Blender has been great so far, easy to add, remove or edit the hair cards and I think my favorite feature is being able to draw my curves right on the head mesh. This makes for quick iterations and adjustments which I send over to Marmoset to view in realtime. I’ve also played around a little bit with expressions, seeing Steve Carell so straight-faced is out of character and for me makes it a bit harder to see if I am hitting the features right.
