Control (UI) Default Value Function
curve_mode ribbon Sets curve display to ribbon, thick, or oriented. Ribbon
renders curves with costant orientation (perpendicular to the
camera), thick renders curves as a pil, and oriented renders
curves with variable orientation.
All curve types respect the following attributes, set on the curve
geometry Scene Graph location:
• geometry.constantWidth - A single float specifying a width
value to apply to each control point in the curve.
• geometry.point.width - An nX1 tuple of floats, where n is the
number of control points in the curve. Specifies a separate
width for the curve at each control point.
• Note: If geometry.constantWidth and
geometry.point.width are both set, the values in
geometry.point.width are applied.
• If the curve type is oriented, a further, optional attribute can
be set on the curve geometry Scene Graph location:
• geometry.point.orientation - An nX3 tuple of floats, where
n is the number of control points in the curve. Specifies the X,
Y, Z orientation of each point.
curve_basis b-spline Sets the function used to approximate the curve.
min_pixel_width 0 Only applies to curves primitives. Enables pixel width
enlargement, for improved anti-aliasing.
Shading
receive_shadows On Sets whether or not the object receives shadows.
self_shadows On Sets whether or not the object is able to cast shadows on itself.
Shading > Volumetrics
step_size 0
Shading > Displacement
disp_padding 0 Sets the amount of padding or spacing on displacement
bounds.
