nxQuestion enables the design and production of sophisticated particle effects and behaviours using a layering system of questions, actions, variables, loops and scripts.

The way in which nxQuestion is utilized will depend upon your level of knowledge or area of expertise.

At its simplest, nxQuestion enables the intuitive triggering of actions based on particle questions; for example, ‘If a particle’s radius is greater than 3cm, then turn it blue.’

At its most complex, custom GLSL scripts can be written and used within nxQuestion to create bespoke effects.
