This is the general procedure for creating a Particle Sampler Info node. These are general steps—we’ve included examples of specific tasks in Examples of using the Particle Sampler Info node.
To create a Particle Sampler Info node
This displays the Connection Editor with the Particle Sampler Info node on the From side and the shader on the To side.
In the case of color, transparency, and incandescence, the Connection Editor is not displayed when you click the Particle Sampler Info button. Instead, Maya creates the new Particle Sampler Info node for you, and automatically makes the following default connections:
The connection between the particle shape and the Particle Sampler Info node is implicit— you don’t actually make it. The only connection you make is between the Particle Sampler Info node and the shader.
