xpInfectio simulates growth patterns.

It is modeled on the idea of an infection spreading from one particle to another, but you can use it for any kind of growth.

In this animation, nxInfectio starts operating from the two Seed Objects, which have been added to the scene (see parameter description on this page) and continues its life cycle, determined by the settings chosen.

Add New Seed Object

Click this button to create a new Seed Object and add it to the scene as a child object of the xpInfectio modifier.

Note: Without at least one seed object, the modifier will not work and all the parameters will be disabled until a seed object is added.

Enabled

Checking this box enables the xpInfectio modifier.

Mode

Set at Independent, by default.

You can change this to Action-Controlled.

Independent Mode

In this mode, particles will be affected if they come into the field of effect of the modifier.

Action-Controlled Mode

When in the Action-Controlled setting, the modifier will only act on a particle when told to do so by an action.

Until that point, the particle will not be affected, but once activated for a particular particle, the modifier will influence the particle - that is, it will play back the history.
