This is an adaptation of the 'long2' hairstyle (MH alpha 7 version). The licence was GPL, but author was set to unknown. So I consider it CC BY, but the author is the MH team. The adaptation was changing the position and the texture a bit, so that the hair looks slightly better. The example picture is from MH and shows the asset on my 'Evi' character. Edit: small fixes done to the .mhmat file to keep Blender happy without changing the material.
