Public Attributes#

Type	Name	Visual Hint	Description
`string`	`prim_path`	`VISUAL_HINT_DEFAULT`	Prim path in the USD stage.
`string`	`purpose`	`VISUAL_HINT_DEFAULT`	Purpose of this prim.
`long`	`frame`	`VISUAL_HINT_FRAME`	Define the frame value used to evaluate the geometry.
`long`	`frame_offset`	`VISUAL_HINT_FRAME`	Define the frame offset. Example: if the frame offset is 50 while the animation starts at frame 10, then it will start at frame 60.
`long`	`animation_behavior`	`VISUAL_HINT_DEFAULT`	Define the animation loop behavior.
`bool`	`force_animation_range`	`VISUAL_HINT_DEFAULT`	Enable the defined animation range, used to override the object's original animation range.
`long[2]`	`animation_range`	`VISUAL_HINT_FRAME`	Start and end frames for the animation.
`long`	`motion_blur_mode`	`VISUAL_HINT_DEFAULT`	Specify which data is used by the motion blur. It can use simple velocities that are either read from the file or computed from positions. Or it can use sub-frame positions which gives a better result but which requires more memory.

Inherited Public Attributes#

Type	Name	Visual Hint	Description
`double[3]`	`translate`	`VISUAL_HINT_DISTANCE`	Set the XYZ position of the item relative to its parent item.
`double[3]`	`rotate`	`VISUAL_HINT_ANGLE`	Set the XYZ rotation of the item relative to its parent item.
`double[3]`	`scale`	`VISUAL_HINT_SCALE`	Set the XYZ scaling of the item relative to its parent item.
`double[3]`	`shear`	`VISUAL_HINT_SCALE`	Set the XYZ shear of the item relative to its parent item.
`long`	`rotation_order`	`VISUAL_HINT_DEFAULT`	Specify on which order the Euler rotations are composed. By default Clarisse's uses YXZ
`reference` (`SceneItem`)	`parent`	`VISUAL_HINT_DEFAULT`	Set the parent item of the item.
`bool`	`inherit_transform`	`VISUAL_HINT_DEFAULT`	Does the current object inherits its parent transformation ?
`long`	`reference_frame`	`VISUAL_HINT_FRAME`	Set the reference frame that defines the base transform and deformation state of the item. This reference is used when computing texture projections or when generating point cloud (in Global Base) on the base geometry.
`object[]` (`Constraint`)	`constraints`	`VISUAL_HINT_DEFAULT`	Stack of constraint operators. Constraints like Target, Point, Orient... are applied to a Scene Item in order to drive the transformation of the item.
`double[3]`	`scale_pivot`	`VISUAL_HINT_DISTANCE`	Set the coordinates of the scale pivot.
`double[3]`	`rotate_pivot`	`VISUAL_HINT_DISTANCE`	Set the coordinates of the rotation pivot.
`double[3]`	`translate_offset`	`VISUAL_HINT_DISTANCE`	Set the XYZ position of the pivot point of the item.
`double[3]`	`rotate_offset`	`VISUAL_HINT_ANGLE`	Set the XYZ rotation of the pivot point of the item.
`double[3]`	`scale_offset`	`VISUAL_HINT_SCALE`	Set the XYZ scaling of the pivot point of the item.
`long`	`rotation_offset_order`	`VISUAL_HINT_DEFAULT`	Set the rotation axis mode.
`bool`	`display_visible`	`VISUAL_HINT_DEFAULT`	Set whether the item is shown in the 3D View or not.
`bool`	`display_pickable`	`VISUAL_HINT_DEFAULT`	Set whether the item is pickable in the 3D View or in the Image View.
`long`	`display_color`	`VISUAL_HINT_DEFAULT`	Set the item color for constant or simple shading display in the 3D View.
`double[3]`	`display_custom_color`	`VISUAL_HINT_COLOR`	Set the item custom color used for display in the 3D View when the Display Color attribute is set to Custom.
`long`	`visibility_mode`	`VISUAL_HINT_DEFAULT`	Set how visibility attributes 'Display Visible' and 'Unseen By Renderer' are driven. In Use Project Preferences mode, the mode uses the project preference value. In Override mode, the attributes are set manually. In Use Property mode, the attributes are driven by a property (e.g. Alembic visibility property).
`bool`	`enable_motion_blur`	`VISUAL_HINT_DEFAULT`	Set whether the renderer will do motion blur on the item or not.
`long`	`display_mode`	`VISUAL_HINT_DEFAULT`	Define how the object is displayed in the 3D View.
`long`	`highlight_mode`	`VISUAL_HINT_DEFAULT`	Define how the object is highlighted in the 3D View when selected.
`reference` (`Material`)	`override_material`	`VISUAL_HINT_DEFAULT`	Setting a material here will set the specified material to all elements of the scene object. Ex: all shading groups of a geometry will have the same material. Ex: all elements of a combiner or a scatterer will have the same material.
`bool`	`matte_object`	`VISUAL_HINT_DEFAULT`	Switch the object to 2D matte mode.
`double[3]`	`matte_color`	`VISUAL_HINT_COLOR`	Set the color of the object in matte mode.
`double`	`matte_alpha`	`VISUAL_HINT_PERCENTAGE`	Set the opacity of the object in matte mode. When the matte alpha is less than 100%, the object creates a hole in the layer as no transparency is evaluated.
`long`	`custom_id`	`VISUAL_HINT_DEFAULT`
`double`	`raytrace_offset`	`VISUAL_HINT_DISTANCE`	Set the minimum distance for raytracing visibility. If the ray hit point distance from the ray source position is smaller than this value, then the geometry is not seen. Note: this attribute is used to prevent self intersection artifacts.
`string`	`shading_variables`	`VISUAL_HINT_SCRIPT`
`bool`	`unseen_by_renderer`	`VISUAL_HINT_DEFAULT`	Set whether the object is hidden from the renderer or not.
`bool`	`unseen_by_camera`	`VISUAL_HINT_DEFAULT`	Set whether the object is hidden from the camera (primary rays) or not.
`bool`	`unseen_by_rays`	`VISUAL_HINT_DEFAULT`	Set whether the object is hidden from the raytraced shading effects like reflection/refraction (secondary rays) or not.
`bool`	`unseen_by_reflections`	`VISUAL_HINT_DEFAULT`	Set whether the object is hidden from reflections or not.

`bool`	`receive_self_shadows`	`VISUAL_HINT_DEFAULT`	Set whether the object receives self shadows or not.
`reference` (`Group`)	`lights`	`VISUAL_HINT_GROUP`	Specify the group of lights that illuminate this object. By default, scene objects are lit using the lights gathered by the 3D layer.
`object[]` (`Deformer`)	`deformers`	`VISUAL_HINT_DEFAULT`	List of deformation that will be applied on the geometry.
`double`	`smoothing_approximation`	`VISUAL_HINT_PERCENTAGE`	Controls how much the smoothing must be approximated during the shading. This influences the origin of secondary rays casted from the surface. A value of 0% corresponds to the position that has been found during the raytracing and a value of 100% corresponds to the theoretical position on the smoothed surface.
`double`	`decimate`	`VISUAL_HINT_PERCENTAGE`	Set the decimation amount.
`long`	`shape`	`VISUAL_HINT_DEFAULT`	Specify how hair are rendered.
`double`	`flatness`	`VISUAL_HINT_PERCENTAGE`	Flatness of the hair. A value of 1 creates round hair, a value of 0 creates flat hair.
`long`	`radius_values`	`VISUAL_HINT_DEFAULT`	Override radius values stored in the geometry by the one set below.
`double`	`base_radius`	`VISUAL_HINT_DISTANCE`	Radius of the hair at its base.
`double`	`tip_radius`	`VISUAL_HINT_DISTANCE`	Radius of the hair at its tip.
`double`	`radius_multiplier`	`VISUAL_HINT_PERCENTAGE`	Hair radius is multiplied by this value.
`bool`	`use_normal_map`	`VISUAL_HINT_DEFAULT`	Set whether ribbons should be oriented according to the first available normal map. When disabled, the ribbons are facing the camera.
