Karma XPU is production-ready and works with new Solaris tools such as the Material Linker, Material X Galleries and Shot Clones.


The ability to access the speed of the GPU to render with Karma was introduced with the last Houdini release. Now Karma XPU is production-ready as it reaches feature parity with Karma CPU in key areas and integrates well with the Solaris lookdev and lighting environment.

When working in production, information about every aspect of the rendering process can help you make key decisions.  Houdini and Karma will now send critical information to the Render Stats panel or to a detailed HTML report.

Materials & Textures

With Karma XPU Material X is used to build shaders for your scenes. Through the Material Linker in Solaris you now have access to a Gallery of materials that can be applied with a drag and drop interface.

Solaris Clone Workflow

While rendering in Solaris, you can now create clone processes for different cameras, shots or even points in time. These clones can be rendered locally or on the render farm and allow for fast parallel processing for quick evaluation of key aspects of your scene.

Note: The bundled licenses can be used BOTH locally and on your render farm/cloud.

This new price took effect on Jan 1, 2024. Speak to your Account Manager about volume pricing.
