How would you go about this guy's fur? I'm sculpting this dragon and, so far am pretty happy with how it's turning out. However, I am not sure how I should go about modeling his fur. The target platform is the unreal engine 4 but for now I am just trying to get a nice model before retopology.
I think your best bet would be to create a group of mesh hair objects, and then use a particle system in Blender to place and arrange them as needed. 

Then before importing into Unreal Engine, you'll have to apply the particle modifier and convert the hairs into mesh objects.
