spline to shape

 

 

This node will convert a spline shape into the particle shape by placing a skin based on another 2D shape. New shape will be divided in segments by the spline knots location.

 

 

[Inputs]

 

Enabled - Enable or disable node evaluation.

 

#Splines - Connect any number of splines (from particle to spline node) to this pin.

 

Shape Particle Group - Once the geometry is created it will be assigned to a new particle as a particle shape. Select the particle group for the new particle from the list.

 

Seed - Random number generator seed value.

 

Shape

Shape Type - Defines the shape that will be used to skin the spline.

• Simple - A simple shape will be used for a skin.
• Custom - Pick any 2D shape for spline skin.

 

Size - Defines the number of sides for a simple shape.

 

Custom Shape - Select any 2D shape from the scene to be used for the spline skin.

 

Segments - Allows you to refine the custom shape shape.

 

Optimize - The shape can be optimized based on the spline curvature regardless on the number of spline knots. For example, a straight line would only need the first and the last knot.

 

Threshold - The spline curve tangent angle difference that will be considered as a threshold that will trigger a new segment.

 

Cap Start - Adds the cap at the spline start.

 

Cap End - Adds the cap at the spline end.

 

Smooth Sides - Sets the spline skin smooth flags.

 

Skin

Radius Scale - Skin radius is defined at the spline knot. Use this parameters to scale up or down the overall skin radius.

 

Radius Scale Var % - Radius Scale variation by spline.

 

Rotate - Sets uniform skin rotation.

 

Rotate Var % - Rotation variation along the spline.

 

Twist - Adds continuous skin rotation along the spline.

 

Twist Var % - Twist variation by spline.

 

Squash - Squash skin shape

 

Squash Var % - Squash variation by spline.

 

Material ID

From Particle - Whole shape will inherit material ID from the first particle that created the spline.

 

Cap Material ID - Material ID for the caps.

 

Sides Material ID - Material ID for the skin sides.

 

UV Mapping

Scale U - The scaling factor the U coordinate.

 

Scale U Var % - Scale U variation by spline.

 

Scale V - The scaling factor the V coordinate.

 

Scale V Var % - Scale V variation by spline.

 

Offset U - The offset for the U coordinate.

 

Offset U Var % - U coordinate offset variation by spline.

 

Offset V - The offset for the V coordinate.

 

Offset V Var % - V coordinate offset variation by spline.
