Houdini - Karma Material Particles AOV for Karma CPU & XPU - IPOPs (Image Plane Operators)

What are IPOPs?

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 Particles AOVs

The Particles 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

  4. Karma MaterialX - Karma CPU & XPU
