Really love this hair and it works in iclone/cc4 just fine. However, please be aware that it has some degenerative triangle issues, so whilst it will import into Unreal, the hair physics in unreal will not work because of the mesh error. Only the Author can fix this issue. If an update can be provided that has these triangles fixed (its only a few according to Unreal) then I would happily change it to a 5 star, because it is one of the best hairs available (outside of RL Hair builder)
Thank you for your purchase. The extended license does not guarantee compatibility with all other companies' software. It only means that it is "exportable".
Since I do not use Unreal, I am not considering modifying the model at this time if there are no problems with CC4 and iClone8.
