The operators described in this section are utilities to help you manage Particle Flow systems.
Topics in this section
Camera Culling Operator
Camera Culling reduces the geometry load in the viewports and/or at render time by filtering out all particles outside the camera frustum (that is, not visible to the camera). You can also use this operator as a group selection tool to define a group by the camera view frustum.
Camera IMBlur Operator
The Camera IMBlur operator corrects a problem in which Image Motion Blur applied to a Particle Flow system might not render properly when the camera is animated. The operator adjusts the particle speed, accounting for camera motion, before it's passed to the viewport display and/or the renderer. Internally, the Particle Flow engine continues to use the true particle speed for the animation.
Display Operator
The Display operator lets you specify how particles appear in the viewports.
Display Script Operator
The Display Script operator is a diagnostic tool that lets you display data associated with each particle in the viewports. For each occurrence of the operator in an event, you can show the particle ID, a label that you provide, and a single datum: float, integer, or vector. The displayed data is generated by a Script operator that precedes Display Script in the event.
Force Operator
The Force operator lets you influence particle motion with one or more space warps from the Forces category. Use this operator along with different forces to simulate the effects of wind, gravity, and so on.
Notes Operator
The Notes operator lets you add a textual comment to any event. It doesn't have any direct effect on the particle system, but it helps you keep track of the overall function of each event.
Render Operator
The Render operator provides controls related to rendering particles. You can specify the form that rendered particles are to take, and how to convert the particles to individual mesh objects for rendering purposes.
Script Operator
The Script operator enables control of particles within the Particle Flow system using a MAXScript script. The script can use any program functionality available to MAXScript.
Stop Operator
Use the Stop operator to halt particles immediately; you can stop particles' linear motion or rotational motion, or both. Alternatively, use the Stop Gradually test to cause particles to slow down and then stop.
