You can publish multiple attributes to a single published name on an asset. This allows you to control all the attributes with a single field or widget on the asset (for example, a network of particles).
To do this, you must first create a Dynamic Attribute that controls the particular attribute on all the internal nodes. Then you can publish that Dynamic Attribute to the asset.
For more information on setting up Dynamic Attributes, see Add dynamic attributes.
