Adjusting Particle Properties Using Curves

With the ParticleCurve, you can apply a curve to particle properties (such as size or mass) to change them over time.

1.

Connect the node to your particle node stream.

2.

Adjust the curves in the ParticleCurve properties panel. The x axis represents the lifetime of the particles.

• r - adjust the curve for the red channel.

• g - adjust the curve for the green channel.

• b - adjust the curve for the blue channel.

• a - adjust the curve for the alpha channel.

• size - adjust the curve for the size of the particles.

• mass - adjust the curve for the mass of the particles.

A size curve modifying the particles to grow in size toward the end of their lifetime.

Note:  If you’re using an image or a 3D object as your ParticleEmitter’s particle input, the ParticleCurve might not alter the colors of the particles as expected.

3.

If you want, you can adjust the curve for your particles’ alpha channel so that each particle fades to invisibility toward the end of its lifetime.
