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.
Features
BRUSH
Options
Enable 3D Brush: When a guide’s second point from the root is in the brush area, 3D brushes can work normally.
Auto Switch: When enabled, the brush is toggled between 3D mode and 2D mode when it’s on or off the geometry. When disabled, there is no brush when it’s off the geometry.
Brush Scale: When enabled, the brush can keep its scale in 3D space. When disabled, the brush can keep its scale in 2D space.
Comb brush
When Preserve Root Length is unchecked, guides can be moved along the surface of geometries. If you want to move the guides away from the surface, you can select the default Comb brush.
Smooth Brush
Length: Smooth the guides to make them average in length.
Add Brush
Length Brush
Target Length: It’s the limit when the guides are lengthened or shortened.
Notice: It doesn’t work when set to 0.
Puff Brush
Weight Brush
Increase, Decrease, Smooth: Modify weight smoothly
Strength: The strength of the weight brush.
Note: Left click somewhere in 3D space to activate weight display, and the same operations to disable it when switching to other brushes.
Orient Brush
Orient, Sunder, Repel:
Orient brush only changes the orientation of the guides while keeping the original shapes. With the Curve enabled, the guides will be bent slightly.
Bend Brush
Bending guides.
Attract Brush
Creating clamps.
Noise Brush
Use Roughness: It works the same as the Roughness in the Children.
Axes Locking: Disable the noise on one or more axes as per the locked axes.
Part Brush
Modifying the orientation of the guides only.
Clone Brush
Clone Source: Pick the source of the guides to be cloned.
Clone Draw: Clone the guides at the position where this brush stays.
Rotation Angle: The rotation angle of the clone brush which can also be achieved with the shortcut—CTRL + MOUSE WHEEL
Clump Type
Parent: Clumps are generated according to the guides. Blender can run faster in this mode when a large amount of clumps are required.
Subdivision: Split the clumps into multiple parts.
Note: The integer is needed.
Generated: Clumps can be generated randomly on the surface, and the amount is controllable without any influence of parent clumps. If you want to attract some clumps which have different parents, this type can help. Blender may run slower in this mode, and it’s recommended to use this type when only a few clumps are needed.
Seed: Random seed.
Randomness: The randomness of clump distribution.
Density: The larger it is, the more but finer the clumps will be.
Kink: Basically the same as in Blender.
Kink Type: Curl, Radial, Wave, and Braid.
Curl: There are 2 types available.
Amplitude: The amplitude of the offset, which can be controlled by a curve.
Orient: An additional option under Wave that controls the orientation of the wave and randomizes the orientation of the wave.
Frequency: Same as the default parameter.
Shape: Same as the default parameter in Blender, and can be controlled by a curve.
