Redshift Volume Setup

Setting up volume materials in Redshift for Houdini

Setup Overview

For proper volume rendering in Redshift, you need to:

  1. Create a separate SOP in the object context specifically for the volume
  2. Apply a volume-specific material to this SOP
  3. Set up the Redshift material with proper volume connections

Volume SOP Setup

Create a dedicated SOP for your volume in the object context:

Material Assignment

Apply a volume material to the SOP:

Redshift Material Setup

In the Redshift Material Builder:

  1. Remove the default surface connection
  2. Add a Redshift Volume node
  3. Connect the Volume node to the volume input

Important Notes

  • Keep volume geometry separate from other geometry for better control and optimization
  • Use volume-specific parameters in the Redshift Volume node for fine-tuning the look
  • Consider using multiple scattering for more realistic results, though it will increase render time
