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.
