Editing Creating Flat Brushes In Procreate (section)

== Brush Studio controls ==

=== Taper ===
* Drag both controls all the way to side for '''Pressure Taper''' and '''Touch Taper'''. 
* '''Size''': None
=== Shape ===
* '''Shape source'''. Select a source that is skinny and oriented so that it is tall and not short. The grain comes from '''Grain''', so solid shapes work better here over distressed shapes.
* '''Count''' multiplies the sampling of the brush shape, effectively making strokes darker.<br />This is typically used with '''Scatter''' and '''Rotation''' to increase the number of stamps at each point where stamp is applied. 
* '''Azimuth''': turn on. This makes for a chisel-edged calligraphy style brush where some strokes are thick and other are thin.
* '''Brush Roundness Graph''' The green control will determine the orientation of the brush shape.
** For a flat brush this means that this direction is the direction where the brush will be the most flat. 
** When the apple pencil is held at a 90&deg; angle to the green dot vector the brush will be at its thinnest, as if the brush is being applied on its side.
=== Grain ===
In order to see streaks in a flat brushes as if seeing the bristles unevenly applying pigment, use a texture that has variation between lights and darks distributed evenly in both an up-and-down direction and side-to-side. If the texture contains a strong horizontal or vertical grain, the bristle effect will be visible in one direction, but will be blurred out when moving the brush perpendicular to that direction.
* '''Grain Behavior''': Moving
* '''Movement''' will allow the grain to follow along with the brush stroke. On the high end of the spectrum, the grain texture is like a static screen through which the stroke is filtered, similar to setting '''Grain Behavior''' to "texturized". The low end creates more "drag" as if the grain texture follows the stroke. 
* '''Scale''' has a large effect on the impression of bristle size. '''Scale''' increases the size of the grain texture as if the source image was scaled up.
** Low scale values simulate fine bristles. 
** High scale values emulate coarser bristles. 
* '''Zoom''' Zoom scales the grain texture relative to the brush shape source. 
** All the way to the right is "cropped" which means that the grain texture size stays fixed and doesn't change as the brush size is increased or decreased. 
** All the way to the left if "follow size" which means the grain texture stays constant relative to the brush tip shape independent of brush size.
* '''Depth''' adjusts the strength of the grain texture as it is combined with the brush stroke. 
** Minimum negates the grain texture.
** Maximum makes the grain texture high contrast within the brush stroke.
* '''Brightness''' and '''Contrast''' can soften the grain or make it more vivid.
