3D Hair Brush is a powerful hair tool, including 3D brushes with Pie Menu, Use Radius Curve, Use Diameter Random, and Hair Modifier.
3D brushes can distinguish complex muscle surfaces of models and provide artists with a wonderful experience of grooming hairstyles in Blender; With multiple well-designed brushes presets, it gives efficient solutions to making varying hairstyles;
Using Radius Curve makes it convenient for us to control hair shape;
Using Diameter Random makes it possible to randomize the thickness of hair in just one particle system.
Modifier gives us an opportunity to add modifiers layer by layer until we get a good result and it doesn’t destroy any hair shape we created before.
