Volume AOVs - IPOPs (Image Plane Operators) for Houdini - Karma Material - Karma CPU & XPU



 

What are IPOPs for Houdini?

IPOPs are operator workflows designed to streamline shaders and AOV development in Houdini. With our toolset, artists can easily standardise their networks and access specially developed nodes for various renderers and presets, increasing efficiency and creativity.





The Volumes AOVs

The Volumes AOVs is a set of HDAs that help artists generate quick AOVs Passes and Mattes that are useful for Compositing and Shading. The HDA library is constantly updated with new nodes to assist artists in speeding up their workflow and creating a streamlined system thereby increasing efficiency and creativity.


Supported Renderer:

  1. VEX Shaders - Mantra

  2. VEX Shaders - Karma CPU

  3. Karma Material - Karma CPU & XPU
