Primitive Affector

Use basic primitives to affect the field.
Primitive Affector
Method #
This node uses basic geometric shapes to affect the field, by attracting or repelling the ink with respect to the selected primitive surface.
The outputs from this node are just its transforms, useful for having multiple nodes follow the same motions without controlling each of their transforms individually.
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 The objects position along the local x-axis.
Position Y The objects position along the local y-axis.
Position Z The objects position along the local z-axis.
Rotation Heading The objects rotation around the local y-axis.
Rotation Pitch The objects rotation around the local x-axis.
Rotation Bank The objects rotation around the local z-axis.
Scale X The objects scale along the local x-axis.
Scale Y The objects scale along the local y-axis.
Scale Z The objects 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 Primitive Type Choose which primitive shape is used for the affector.
- Sphere : Use a sphere to affect the field.
- Box : Use a box to affect the field.
- Cylinder : Use a cylinder to affect the field.
- Plane : Use a plane to affect the field.
- 2D Grid : The field is affected by the edges of a 2d wireframe grid.
- 3D Grid : The field is affected by the edges of a 3d wireframe grid.
- 2D Noise : Uses a 2D noise field to affect the field.
- Wireframe Sphere : The field is affected by the edges of a 3d wireframe sphere.
Velocity Mode Toggle whether the velocity attracts to the primitive or repels away from a primitive.
- Repel : Push the field away from the primitive shape selected.
- Attract : Pull the field towards the primitive shape selected.
Use Colours Allows the colour of the primitive to be blended into the field.
Radius The outer radius for which the affector is active.
Randomness The randomness of the new velocities added to the simulation.
Velocity Randomness Adds a randomness to the velocity of the field.
Velocity Scale Scale the generated affector velocities.
Weight How much the affector affects the field system.
Colour Weight The amount by which the colour of the primitive is blended into the field, if Use Colours is enabled.
Stickiness Controls how much the particle sticks to the surface of the shape once it reaches it.
Affector Mode The method by which the affector is applied to the field.
- Force : The results of the affector are added to the simulation as forces.
- Velocity Modifier : The results of the affector are added each frame after the results of the simulation, and not injected into the simulation itself.
Modulate By Velocity The strength of the affector is modulated per cell by the magnitude of the velocity of the cell, so movement is stronger in faster-moving areas.
Modulate By Temperature The strength of the affector is modulated per cell by the temperature of the cell, so movement is stronger in hotter areas.
