BirthStream - superclass: helper; super-superclass:node - 14:0 - classID: #(1935830531, 515064320) Description:
The BirthStream operator generates a stream if non-overlapping particles and defines their position and speed properties.
Available in 3ds Max 2014 and higher.
Constructors:
BirthStream...Properties:
<BirthStream>.Emit_Start     Integer    default: 0   --  integerGet/set the value of the "Emit Start" spinner.
<BirthStream>.Emit_Stop     Integer    default: 4800   --  integerGet/set the value of the "Emit Stop" spinner.
<BirthStream>.Rate     Float    default: 60.0   --  animatable; floatGet/set the value of the "Rate" spinner.
It defines the emission rate per second.
<BirthStream>.Separation     Float    default: 1.0   --  animatable; worldUnitsGet/set the value of the "Separation" spinner.
It defines the minimum distance in world units between newly born particles.
<BirthStream>.Delay_Birth_If_Overlap     BooleanClass    default: true   --  booleanGet/set the state of the "Delay Birth If Overlap" checkbox.
When set to True, the birth of the particle may be delayed to avoid overlapping.
<BirthStream>.Speed     Float    default: 300.0   --  animatable; worldUnitsGet/set the value of the "Speed" spinner.
Defines the initial speed of the particle.
<BirthStream>.Inherit_Icon_Movement     BooleanClass    default: false   --  booleanGet/set the state of the "Inherit Icon Movement" checkbox.
When set to True, the particle will inherit the speed of the icon.
<BirthStream>.Multiplier     Float    default: 100.0   --  animatable; percent; Controller Scaling: (1 : 100.0); Get/set the value of the "Multiplier %" spinner.
When .Inherit_Icon_Movement is set to True, controls the percentage of the icon's speed to inherit.
<BirthStream>.Icon_Type     Integer    default: 0   --  integerGet/set the state of the "Stream Source Icon" type radio buttons.
Possible values are:
0 - Rectangle (default)
1 - Ellipse
<BirthStream>.Icon_Length     Float    default: 10.0   --  animatable; worldUnitsGet/set the value of the "Lenght" spinner.
<BirthStream>.Icon_Width     Float    default: 10.0   --  animatable; worldUnitsGet/set the value of the "Width" spinner.
<BirthStream>.Color_Type     BooleanClass    default: true   --  booleanGet/set the state of the "Color Coordinated" checkbox.
<BirthStream>.Random_Seed     Integer    default: 45325   --  integerGet/set the value of the "Seed" spinner.
<BirthStream>.Max_Attempts     Integer    default: 100   --  integerGet/set the value of the "Max Attempts" spinner.
