Installation

To use this Node, you must enable wip.genproc.core in the Extension Manager.

Inputs

Name	Type	Description	Default
curve	bundle	Curves to extrude along
section	bundle	Cross section
curveSamplesPerSegment	int	When this is more than 1, curves are sampled at multiple points along each curve segment.	1
sectionSamplesPerSegment	int	When this is more than 1, cross sections are sampled at multiple points along each curve segment.	1
reverseSectionVertexOrder	bool	When enabled, cross section vertices will be wound in reverse order, in order to flip the geometric normal direction of the surface.	False
generateSTs	bool	When enabled, generate STs using the method selected by projectSTs.	False
projectSTs	bool	When generateSTs is on, this being enabled indicates to generate STs that are just the points projected into the XZ plane, else generate STs based on distances along the curves and cross sections.	False
normalizeS	bool	When enabled, if projectSTs is off, the S coordinate will be normalized to go from 0 to 1 around the cross section.	True
flipS	bool	When enabled, if projectSTs is off, the S coordinate will be replaced with 1-S, flipping appearance of textures.	False
stScale	float[2]	Generated STs will be scaled by this.	[1.0, 1.0]
travellingT	bool	When enabled, the S coordinate will be incremented by travelling instead position	False
centerSectionAtOrigin	bool	When enabled, translate the cross section such that the center of its bounding box is at the origin, before applying any other transforms.	True
sectionScale	float	Cross section points will be scaled by this, after optionally centering it at the origin, but before applying any other transforms.	1.0
sectionRotation	float[3]	Rotates the cross section by this after applying scales specified here, but before applying the translation specified here, and before applying the rotation and translation due to each curve point.	[0.0, 0.0, 0.0]
sectionRotationOrder	int	Order in which to apply the rotations in sectionRotation: 0=xyz, 1=xzy, 2=yxz, 3=yzx, 4=zxy, 5=zyx	0
sectionTranslation	vectorf[3]	Translates the cross section by this after applying scales and rotations specified here, but before applying the rotation and translation due to each curve point.	[0.0, 0.0, 0.0]
rampPositions	float[]	Positions for the scale ramp, in the normalized distance along curve space, from zero to one: zero being the beginning of the curve, and one being the end of the curve.	[]
rampValues	float[]	Scales for the scale ramp to be applied to the cross sections.	[]
rampInterpolations	int[]	Interpolation curve types for each segment of the scale ramp. Linear (1) creates a flat curve from point to point in the ramp. Smooth (2) creates an ease in or ease out curve from point to point in the ramp.	[]
up	vectorf[3]	Initial up vector to use for orienting the cross section around the first point of each curve. This will be forced to be perpendicular to the start of each curve, so for stability, it’s best if it’s not close to parallel to the start of any curve.	[0.0, 1.0, 0.0]
upMethod	int	The way in which to apply the specified up vector. Current supported methods are: 0 = at every curve sample; 1 = at start of curve & minimize rotation along curve	0
