Volume Shadow Shading - Notch Reference Manual

Method

This node shades particles using a shadowing function from the point of view of a Light Node connected to the Light Node input. The shadow effect takes into account transparency of particles, so light will appear to be partially absorbed by particles rather than completely blocked by them. The Particle Alpha parameter is used to scale the transparency of the particles when calculating the shadow effect. The Particle Use Amount parameter is used to reduce the number of particles used for generating the shadow, which may also increase performance.

This node is only effective if a light is connected to the Light Node input. The light node must be a spot light.

Example
