Volume Shadow Shading
Updated: 27 Mar 2024
Light particles using shadow volumes.
Volume Shadow Shading
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.
This node is only effective if a Light is connected to the Light Node input. The light node must be a spot light.
Parameters
These properties control the core behaviours of the node.
Parameter Details Particle Size
Edit the size of the particles once they are rendered.
Particle Alpha
Control the alpha value for each particle.
Particle Use Amount
Percentage of particles that can be used by the node.
Inputs
