Introducing KATANA 2.5—now on Windows!


KATANA® 2.5 is the latest version of our award-winning lighting and look development software. Now, studios large and small who need to bring greater efficiency to their lighting and rendering pipeline can use KATANA on either Windows or Linux.

In addition, KATANA 2.5 is easier to install, and offers an expanded range of supporting plug-ins, including RenderMan, V-Ray, Arnold and 3Delight.

What else is new in KATANA 2.5?

Color and float ramp widgets

Now you can easily select a range of colors or floating-point grayscale values to use as an input to a shader or light with an intuitive, visual UI that offers a more artist-friendly look development experience than in previous versions. The color and float ramp widgets can be used for parameters directly within KATANA, or added to tools in third-party plug-in renderers.

Gaffer Three light filter support

It’s now possible to add light filters—such as barn doors, blockers or gobos that stop or reduce the effect of a light for certain parts of the scene—directly to lights in Gaffer Three nodes, KATANA’s default lighting tool. This both streamlines the workflow by allowing you to edit all of your lighting information in a single place, and reduces node graph complexity.

Online searchable help and developer documentation

Whether you’re an artist or a developer, having easy access to the help or documentation you need is crucial. Now, KATANA’s user, reference and technical guides have been combined into a single HTML-based, searchable system, while the developer documentation is now presented as an online, searchable developer guide that can be easily and regularly updated.

Performance profiling diagnostics

Diagnosing performance issues in complex projects is now easier, thanks to a new mode that enables KATANA to record the time taken by every step when processing a scene. TDs can export and visualize this data in order to help determine the source of the slowdown, and use their findings to optimize the scene.
