Strategies for using the Particle Sampler Info node

There are two basic strategies for using the Particle Sampler Info node to control your particles:

• The first strategy uses the Particle Sampler Info node to drive a texture placement node. The setup is:

The advantage of this strategy is two-fold: you can use any type of texture, and you can use the controls on the texture placement node.

• The second strategy uses the Particle Sampler Info node to feed per-particle attributes, such as rgbPP, directly to the shading or texture node. The setup is:

The main advantage of this strategy is that it lets you control the per-particle attribute using expressions, ramps, or the Component Editor and see the result in the shading or texture node.

Using the Particle Sampler Info node to drive a texture placement node

Here is an example of the first strategy—using the Particle Sampler Info node to drive a texture placement node, which textures the shader color. In this example, we'll use the particles' age to color the particles.
