Creates a preview animation sequence using either the last settings in the Make Preview dialog or the optional arguments, if provided.

• filename: When specified, saves the output to a file with this path and name. When not specified, uses the default "_preview" name and the path in the #preview system directory.
• outputAvi: When true, outputs to AVI file with the last selected CODEC. When false, outputs to custom file sequence.
• percentSize: Defines the Preview output size as percentage of the current renderWidth and renderHeight values.
• start: Defines the first frame of the Preview animation.
• end: Defines the last frame of the Preview animation.
• skip: Defines the Every Nth frame step of the Preview animation. Corresponds to the "Every Nth Frame" value in the Make Preview Dialog.
• fps: Defines the Frame Rate of the Preview animation.
• dspGeometry: Controls the display of Geometry objects in the Preview animation (except those handled by other flags like Particles and Bones).
• dspShapes: Controls the display of Shape objects in the Preview animation.
• dspLights: Controls the display of Light objects in the Preview animation. This applies to the viewport visibility of the light objects, not to their illumination - they will illuminate the scene even if hidden.
• dspCameras: Controls the display of Camera objects in the Preview animation.
• dspHelpers: Controls the display of Helper objects in the Preview animation.
• dspParticles: Controls the display of Particle objects in the Preview animation.
• dspBones: Controls the display of Bone objects in the Preview animation.
• dspGrid: Controls the display of Home of Custom Grid in the Preview animation.
• dspSafeFrame: Controls the display of Safe Frames in the Preview animation.
• dspFrameNums: Controls the display of Frame Number counter in the Preview animation.
• dspBkg: Controls the display of the Viewport Background in the Preview animation.
• rndLevel: Controls the render level when using the Direct3D Driver. When using Nitrous, the specified vpPreset and vpStyle options are used (see below).
• useMPCamEffect: Controls whether multipass camera effects are performed in the Preview animation. If true, and the current viewport is a camera view with a multipass camera effect defined, the effect is evaluated. Available in 3ds Max 2021.1 Update and higher.
• dspSpaceWarps: Controls the display of Space Warp helper objects in the Preview animation.
• snippet Specifies a snippet of MAXScript code to execute on each frame. The string returned by the snippet is displayed in the rendering output.

These options are NEW in 3ds Max 2024:

• dspCamViewName: Controls the display of the camera or viewport name in the Preview animation. Defaults to true.
• autoPlay: Controls whether the animation automatically plays when the Preview creation is complete. Defaults to true.
• vpPreset: Controls the Per-View preset applied to the active viewport. Defaults to the current active viewport preset.
• vpStyle: Controls the viewport style applied to the active viewport. Defaults to the current style of the active viewport.
• vpEdgedFaces: Controls the display of edged faces in the preview animation. Defaults to true.
• vpTextures: Controls the display of textures in the preview animation. Defaults to false.
