X-Particles contains a system of close control over almost all parameters using Questions and Actions.

No Xpresso is required and everything is done through Cinema’s Object and Attribute Managers in the same way as for other objects.

The system works by asking a ’Question’ of each particle – for example, does the particle age exceed a specified value.

If the particle ‘passes’ the Question, an Action is called which has an effect on the particle, Most Actions work through the particle modifiers but others are independent of them.
