The parameters of all NeXus modifiers can be mapped to particle data, enabling dynamic changes during simulation.

The effects of the mapping are adjusted using the Range Mapping curve.

The settings can be found within the Mapping tab of each object.

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.

Add Layer

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.
