Within class: 

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.


Property group 'MaterialExpressionParticleMacroUV'[edit]


Type: bool

Whether to calculate the UVs in View space, which gives a slightly different UV position based on depth and creates a parallax effect, at the cost of texture swimming.
