Syntax

class UMaterialExpressionParticleMacroUV : public UMaterialExpression

Remarks

This UV node generates texture coordinates in view space centered on the particle system's MacroUVPosition, with tiling controlled by the particle system's MacroUVRadius. It is useful for mapping a 'macro' noise texture in a continuous manner onto all particles of a particle system.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
