I’ve played around with hair sim in Blender 2.53. The whole fur is raytraced, and lit with 2 area lights. I’m having a problem with the left area light which creates the mess on the fur. The strength of the area light is .25 and it’s located around 9BUs from the doll, while the other one is .1 and located some 8BUs to the left. Also, the patchy texture of the fur is not very appealing, and I’d like to fix that as well.
I’ll upload the blend file later today. Meanwhile, if you can give me advice on how to fix these issues, I’d appreciate it.
