Katana + RenderMan
Katana's powerful and flexible look development environment combined with RenderMan's state-of-the-art rendering technology come together to offer the user a remarkable out-of-the-box experience for for high-end lighting and rendering. RenderMan for Katana (RfK) provides seamless access to RenderMan's powerful rendering system for Katana users, who can take advantage of the plugin's flexibility to create an optimal, customized pipeline.
About the Plugin
The RenderMan plugin for Katana plays a dual role in a production pipeline; it is the bridge by which a user generates rendered images from a Katana scene as well as the provider of access to the tools for building the 3D elements within the scene. Although RfK is generally referred to as a "plugin" it is in actually a collection of plugins, nodes, macros and other tools which together allow the Katana user full access to the PRMan rendering system. Included in the RfK plugin package:
- Rendering plugin
- Renderer introspection plugin
- Device drivers for Preview and Live rendering are now combinedinteractive renders
- GafferThree extensions for PRMan lights
- Viewer plugins and manipulators for PRMan lights
- Macros for features such as Denoise and Holdouts
- Nodes for PRMan render configuration
- Tutorial scenes
Vastly improved Live Rendering is iterative rendering where you can change parts of your scene and see it update in the render. Live rendering improves lighting and shading iteration. RfK supports offers the following features:
- Edits to material parameters, adding/deleting, and editing of shading nodes
- Edits to attributes and transform of lights and light filters, including mesh lights.
- Edits to shapes and transforms for objects
- Import and Export assets while Live Rendering
- Object ID picker functionality picking in the Monitor with the pixel probe.
- Addition of lights (analytic and mesh) and object creation during live rendering.
- Live updates of renderSettings (ROI, cropWindow, resolution)
- Live updates of integrators and options (as supported by PRMan)
- Live authoring of AOVs
Lighting and Shading
RenderMan ships with built-in production-quality shaders and lights, the same shaders and lights in use by Pixar Animation Studios on their feature films. Pixar shaders are loaded automatically at startup and available through the standard Material node or the PrmanShadingNodeKatana material workflows. Pixar lights can be created in GafferThree with a single key-stroke or directly via the menu. Mesh lights can also be created by simply selecting the geometry and creating a PxrMeshLight. Viewer Plugins and Manipulators are also included for the built-in lights and light filters.
