Example ParticleBlinkScript Kernels

These kernel examples demonstrate various ways in which the ParticleBlinkScript node can be used.

Coloring Particles

This example kernel is for changing particle color over the course of their lifetime.

Constraining Particles

An example kernel demonstrating how the ParticleBlinkScript node can be used to constrain particles to the surface of a sphere.

Flowing Particles

An example kernel for making particles flow around, or avoid, an object by creating a vector field.

Image Projection

This kernel example projects an image onto the particle system and colors the particles according to their position.
