Use Object Parameter to get a single parameter value from any object in the scene, including modifier settings and Particle Flow operators and tests.
Interface
- Object
- The object from which to derive a parameter. Click this button and then select the object whose parameter you want to use. This adds the object to the suboperator and displays its name on the Object button. Use the Parameter setting (see following) to specify the parameter.
To use a parameter from a Particle Flow element, select the system icon, such as PF Source 001.
- Parameter
- The object parameter for the suboperator to use. After specifying the object (see preceding), click this button to open the Add Parameter Control dialog. Choose the parameter from the list in the dialog and click Add.
- Type
- The data type for the parameter, such as Real or Boolean.
- Subframe Sampling
- When on, provides extra precision with an animated parameter whose value is changing quickly at the subframe level; this is particularly useful when particles come to the event at slightly different times. When Off, the parameter value is queried as of the end of the integration step.
Usually it’s not necessary to turn on this setting even if the parameter is animated. It helps primarily in the specific conditions described above.
- Rename
- To change the parameter name, enter a new name and click Rename. This is useful for giving the parameter a more meaningful name in the context of the suboperator.
- Use As Speed Value
- Internally, the speed of particles in a Particle Flow system is presented in units per tick (1 tick = 1/4800 second). However, the speed parameters in Particle Flow operators are presented as units per second. To translate from the displayed values to internal values, to turn On Use As Speed Value and use the default setting Units Per Second. This way you can access, for example, the speed defined by the standard Speed operator in Particle Flow. Available only when the input parameter is of the Real type.
