Hair is made using Blender particle hair, using 9 different particle systems for the different parts of the hair. The flower is a new idea in character design I’m trying to convince Bassam to go for, please vote in comments to keep the flower!
The following is a turnaround test video to verify that Blender can render the hair without flickering. Good result! Maybe blender internal is not so bad after all 😉
