Well luckily C4d does have an option to reduce the amount of points that it simulates with from the guides. So lowering it down to 1 or 2 at least allows me simulate a very slow version of the hair. I just wanted to know if there was some special C4D hair system features that would allow it to be easier. Unfortunately, Xgen hair is imported just as guides (otherwise the shape from Xgen would be lost). So simulation is understandably slow…
