Summary

Hi Hamed,

As I suggested in your previous posts and emails, you should apply Dynamics under HairFromGuides to avoid this problem. As I tell you by email, we are working to fix this and I will keep you updated, this is going to be solved eventually. For now, please apply the Dynamics node under HairFromGuides. Another workaround is increase the hair density to 100% and use the Animation node to record the simulation as I showed you before.
