Public Attributes#
Type | Name | Visual Hint | Description |
---|---|---|---|
string |
filename |
VISUAL_HINT_FILENAME_OPEN |
Geometry file path. |
long |
pivot_mode |
VISUAL_HINT_DEFAULT |
Set the way pivot information is read in the file: using the baked matrix or individual attributes. |
long |
frame |
VISUAL_HINT_DEFAULT |
Defines the value of the frame that will be used to evaluate the mesh. |
long |

long |
deform_frame_count |
VISUAL_HINT_DEFAULT |
Count of frames available in the file to deform the cloud |
long |
frame_offset |
VISUAL_HINT_DEFAULT |
Offset the time. If you set the value to 50 while the animation starts at frame 10, it then starts at frame 60. |
long |
animation_behavior |
VISUAL_HINT_DEFAULT |
Set how the animation will loop. |
bool |
force_animation_range |
VISUAL_HINT_DEFAULT |
|
long[2] |

Start and end of the forced animation. |
long |

VISUAL_HINT_DEFAULT |
Set how the animation will be deformed. |
bool |

VISUAL_HINT_DEFAULT |
|
long[2] |
deformation_range |
VISUAL_HINT_DEFAULT |

long |
motion_blur_mode |
VISUAL_HINT_DEFAULT |
Specify which data is used to compute motion blur. Read Velocities (distance per second): read velocities from file and interpret them as distance units per second. Read Velocities (distance per frame): read velocities from file and interpret them as distance units per frame. Compute Velocities: compute velocities from actual geometric positions. Use Sub Positions: use sub-frame geometric positions, providing more accurate results at the expense of more memory usage. |

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.

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. |

VISUAL_HINT_DEFAULT |
Define how the object is highlighted in the 3D View when selected. |
long |
custom_id |
VISUAL_HINT_DEFAULT |
|
string |
shading_variables |
VISUAL_HINT_SCRIPT |
|
bool |
unseen_by_renderer |
VISUAL_HINT_DEFAULT |
Set whether the object is hidden from the renderer or not. |

unseen_by_reflections |
VISUAL_HINT_DEFAULT |
Set whether the object is hidden from reflections or not. |
bool |
unseen_by_refractions |
VISUAL_HINT_DEFAULT |
Set whether the object is hidden from refractions or not. |
bool |
unseen_by_gi |
VISUAL_HINT_DEFAULT |
Set whether the object is hidden from global illumination or not. |
bool |
unseen_by_sss |
VISUAL_HINT_DEFAULT |
Set whether the object is hidden from sub-surface scattering or not. |
bool |
receive_self_shadows |
VISUAL_HINT_DEFAULT |
Set whether the object receives self shadows or not. |
bool |
enable_emission_importance_sampling |
VISUAL_HINT_DEFAULT |
Specify whether emission importance sampling is enabled on the scene object. This attribute is ignored when emission importance sampling is disabled in the renderer. |
long |
emission_sample_count |
VISUAL_HINT_SAMPLE_PER_PIXEL |
Override the number of emission samples allocated by the renderer when sampling the scene object. |
long |
emission_texture_importance_sampling |
VISUAL_HINT_DEFAULT |
When None, no texture importance sampling is performed. When Color, Emission Color input textures of all materials assigned to the scene object are importance sampled. This mode should be used when only the Emission Color of the material is textured which is typically the case when using an HDR texture encoding both color and intensity. When Weight, Emission Weight input textures of all the materials assigned to the scene object are importance sampled. This mode can be useful when you explicitly want to vary the color texture according to a spatial projection based on the position of the instance such as world projections, texture switch or instance color for example. Please note that setting this mode while texturing Emission Color can lead to a degradation of the quality of the importance sampling if the intensity/weight component is encoded to the color textures. When Both, both Emission Color and Emission Weight input textures of all the materials assigned to the scene object are importance sampled. This mode should be used when using specific textures for Emission Color and Emission Weight. |
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. |
