Hi, perhaps you have already solved it yourself, because you mentioned to successfully weight painted it? I reply because your particel editing screenshot still shows some “weirdness” ;-).
I opened the file you provided, and looked at your setup. It’s a nice modeling and pretty well done seams! I have not worked with the new cycles hair particles until now but I’m happy that the most settings have remained the same.
First of all, you had 50K particles, so either you have a monster machine or plenty of time For my test I changed that to 1000 particles and 150 children per each particle. That is more memory efficient. As blenderallday said: The defaut length of 4 is way to long. So I set that to 0.06. Your metric system is set to “none”, so we mesure in blender units. That will perhaps have an effect when it comes to rendering (thickness of the hairs).
After that I created a vertex group “all” for your teddy bear went to weight painting. I lowered the weight around the eyes.
This weight painted vertex group is now the definition for the length in the particle system.
E voila - after all it’s fun!
BTW: I practiced the hair particles a lot with blender internal, and especially the lighting was something to get headaches from. Let’s hope that this will be much easier with cycles.
Perhaps you show your results in the focused critique?
