Adjust the display characteristics of the 3D object. These settings don’t affect the render output of the scene; these are for display purposes only in the 3D Viewer.

• off - hides the 3D geometry object.
• wireframe - displays only the outlines of the object’s geometry.
• solid - displays all geometry with a solid color.
• solid+wireframe - displays the geometry as solid color with the object’s geometry outlines.
• textured - displays only the surface texture.
• textured+wireframe - displays the wireframe plus the surface texture.

When enabled, you can make selections as normal in the Viewer. When disabled, points cannot be selected or changed.

Sets how the object is rendered. This control is independent from the display selection, but has the same settings.

• off - hides the 3D geometry object.
• wireframe - displays only the outlines of the object’s geometry.
• solid - displays all geometry with a solid color.
• solid+wireframe - displays the geometry as solid color with the object’s geometry outlines.
• textured - displays only the surface texture.
• textured+wireframe - displays the wireframe plus the surface texture.

Sets the file path of the kernel used for Load and Save operations. BlinkScript kernels use the .rpp file extension.

Click to load and compile the kernel specified in the Kernel File field.

Click to save the current kernel to the location and file name specified in the Kernel File field.

Kernel Source

Enter the kernel you intend to compile or edit the default ParticleDrag to suit your purposes.

Click the Recompile button to see the result of any changes.

Click to recompile the kernel currently in the Kernel Editor. Any compile errors present are displayed on screen.

Click to create knobs for any parameters which don't already have one.

Click to create a group containing a copy of the current node. This can then be saved as a Gizmo if desired.

This defines the probability that any given particle is affected by this node.

For each incoming particle, the op generates a random number between 0 and 1. If the number is greater than the defined probability value, then that particle is ignored and left unchanged.

0.0 - No particles are ever affected.

1.0 - Every particle is affected

Define the minimum required age of a particle for it to be affected by this node. This node only applies to particles which are above this age, where the age is normalized to 0-1.

Define the maximum required age of a particle for it to be affected by this node. This node only applies to particles which are below this age, where the age is normalized to 0-1.

Altering this value produces different results for anything that requires random numbers. It is used in particular for probability but can also be used for the range knobs within a ParticleEmitter.

Sets the region which you want to use to confine the particle effect to. For example, if you choose a sphere, only particles inside that sphere shaped region are affected by particle effects.

• none - all particles are affected as normal.
• sphere, box, half-space, and cylinder - controls the region’s boundary shape.

If enabled, particles outside the region are affected, rather than those inside it.

Select to import or export a channel file:

• Import chan file - import a channel file and transform the region marker according to the transformation data in the channel file. Channel files contain a set of Cartesian coordinates for every frame of animation in a given shot. You can create and export them using Nuke or 3D tracking software, such as 3D-Equalizer, Maya, or Boujou.
• Export chan file - export the translation parameters that you’ve applied to the region marker as a channel file. This is a useful method of sharing setups between artists.

• Match selection position - the region marker is snapped to a new position depending on the points selected.
• Match selection position, orientation - the region marker is snapped to a new position and orientation depending on the points selected.
• Match selection position, orientation, size - the region marker is snapped to a new position, orientation, and size depending on the points selected.

Sets the operation order for scale (S), rotation (R), and translation (T). The possible operation combinations are SRT, STR, RST, RTS, TSR, TRS.

Sets the order of rotation. The possible axial combinations are ZXY, XYZ, XZY, YXZ, YZX, ZXY, ZYX.

Lets you translate the region marker along the x, y, and z axes. You can also adjust translate values by clicking and dragging the axis in the 3D Viewer.

Lets you rotate the region marker around the x, y, and z axes. You can adjust rotate values by holding down Ctrl/Cmd and dragging in the 3D Viewer.

Lets you scale the region marker on the x, y, and z axes.

Lets you scale the region marker simultaneously on the x, y, and z axes.

Lets you skew the region marker on the x, y, and z axes.

When you make changes to the region marker’s position, scaling, skewing, and rotation, these occur from the location of the object’s origin point or pivot. The pivot x, y, and z controls allow you to offset the pivot point and move it anywhere you like - you can even move it outside of the object. Subsequent transformations applied will then occur relative to the new pivot point location.

You can also hold down Ctrl/Cmd+Alt and drag the pivot point to a new location in the 3D Viewer.

Local Matrix

Enable this control to specify matrix values for the object you’re transforming as an alternative to setting transform, scale, skew and pivot values above.
