Spline Attractor
Method #
This node attracts particles towards a spline shape. The particles will flow along the spline towards a goal point which moves from the beginning to the end of the spline at a rate determined by the Spline Rate parameter. The splines used by this node are extracted from a 3D object which must be connected for this node to have an effect. If The object that is connected contains no spline data this node will have no effect.
This node requires a spline to be connected via the spline input.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Parameter Details Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
Scale X Scale along the local x-axis.
Scale Y Scale along the local y-axis.
Scale Z Scale along the local z-axis.
Control the inheritance of the transforms from the parent.
Parameter Details Position Toggle inheritance of the Position from the parent.
Rotation Toggle inheritance of the Rotation from the parent.
Scale Toggle inheritance of the Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details Velocity Scale Scale the strength of the affectors velocity on the particles.
Radius Alter the outer radius at which the affector is no longer effective.
Randomness How much randomness is added in the particles movement.
Spline Rate The rate at which the goal point moves from the start to the end of the spline.
Spline Time Min The minimum point on the spline at which particles will be affected.
Spline Time Max The maximum point on the spline at which particles will be affected.
Life Effect Coeffs How much the particles are affected by the affector at different stages of the particles life cycle. Values 1 and 2 are control points used to control a bezier curve between values 0 and 3.
