Creating Custom Parameters for Particles

You can create your own custom parameters per particle type on a cloud, providing more flexibility when building custom particle behaviors through scripting.

Per-particle attributes are exposed to the Object Model and C++ API. See the SDK Object Model documentation for ParticleAttribute, ParticleType, and ParticleTypeCollection objects.

To access this documentation, you can open the script editor and press F1 or choose Help > SDK Guide from the main menu in Softimage. The particle objects used can all be found under the Object link (the Object Model) in the Scripting Reference.

As well, see the SDK Customization Guide and the Working with Softimage for Developers guide for more information about particles. These guides are also available in the Scripting Reference contents.

To create a custom parameter for a particle type

1. Open a particle type property editor and click the User Parameters tab.

2. Enter a Name for the custom parameter.

3. Select a parameter Type from the list: Integer, Float, Boolean, etc.

4. Click the New Parameter button.

The new parameter is added to the bottom of this property page and becomes a property of the particle type. In the explorer, you can find all custom parameters in the Parameters folder under the PType node. Make sure to use the All Nodes filter to see them.
