Attributes (371)

Attribute quick index omitted (too many attributes to show them all).

Long name (short name)	Type	Default	Flags
outBrush (obr)	dynBrush	NULL
output brush data for use by stroke nodes
time (tim)	time	0film
time value for animated effects
globalScale (gsc)	double	1.0
Scales all effects
depth (dep)	bool	false
whether or not to use zbuffered occusion
modifyDepth (mdp)	bool	true
whether or not to write into the zbuffer( only if depth is ON )
modifyColor (mdc)	bool	true
whether or not to write into r,g,b
modifyAlpha (mda)	bool	true
whether or not to write into the alpha channel
illuminated (ill)	bool	false
Use lights for shading.
castShadows (csd)	bool	false
make brush strokes appear in depth map shadows
lightingBasedWidth (lbw)	double	0.0
The tube width is scaled by the diffuse light intensity. Brighter regions will be thinner. Shadowed and dark regions will have full width tubes. Using negative values can have the reverse effect. The lighting used is a diffuse illumination that is relative to the local surface normal painted on by the stroke.
branches (brc)	bool	false
split tubes into branches
twigs (twg)	bool	false
create twigs as offshoots on branches
buds (bud)	bool	false
create bud swellings at the tips of branches and twigs
leaves (lvs)	bool	false
create leaves on branches and twigs
flowers (flw)	bool	false
create flower petals on branches, twigs and buds
brushType (brt)	enum	0
Method used for brushstamp rendering 0 - Paint Brush 1 - Smear Brush 2 - Blur Brush 3 - Erasor Brush 4 - Thin Line Brush 5 - Triangle Mesh Tube
brushWidth (bwd)	double	0.05
the worldspace width of the brushstroke
screenspaceWidth (spw)	bool	false
whether or not to make the line width constant for different depths from the view
distanceScaling (dsl)	double	0.0
This controls the amount that the distance from the eye affects the tube width when screenSpace width is enabled. At a value of 0.0 the width is constant while at a value of 1.0 it behaves as if screenspace width is OFF.
minPixelWidth (mpw)	double	0.0
When screenspace width is enabled this controls the smallest width a stroke can be in pixels. It is useful for toon lines when one wishes to avoid very thin lines.
maxPixelWidth (mxp)	double	1000.0
When screenspace width is enabled this controls the largest width a stroke can be in pixels. It is useful for toon lines when one wishes to avoid very fat lines.
stampDensity (sdn)	double	8.0
the spacing of stamps relative to brush width
softness (sft)	double	0.2
control for brush edge blurring
edgeAntialias (eaa)	bool	true
EdgeAntialias determines whether or not to antialias brushstroke edges. Note that this does not affect paint or render speed and should be left on unless hard jagged edges are desired.
edgeClip (ecl)	bool	false
EdgeClip allows one to make 3D strokes render as if they are painted directly onto a surface's texture. The edgeClipDepth attribute controls how far in front of a surface the stroke can be before it becomes invisible. Thus 3D strokes that sit close to an objects surface can be seen if the surface is behind them, but not if the surface edge is in profile.
edgeClipDepth (ecd)	double	0.1
EdgeClipDepth controls how close an object behind a stroke must be in order for the stroke to be visible.
occlusionWidthScale (ows)	bool	false
OcclusionWidthScale scale stamp size down based on overlap by forground objects. The full stamp is always drawn, avoiding antialias problems where occluded by non-paint effects forground objects. The size of the stamp is reduced to zero (and thus hidden) when the entire stamp is occluded.
