In this animation, the effects of an nxScale modifier are being mapped to the particle’s age using the remapping curve. The result is the particles are growing and shrinking in size over time.
There are eighteen possible particle data types available, that will map a selected modifier parameter to the particle property.
These are: Age, Color (Brightness), Color R, Color G, Color B, Distance, Document Time, Fluid Density, Granular, Group, ID, Life, Mass, Radius, Scale, Speed, Vertex Weight and Shader.
Layer type drop-down menu.
Clicking on a layer type will automatically put it into the Maps list.
Highlighting the layer type will then present you with the attributes available.
You can have as many layer types as you wish in this list.
