Third-Party Dependencies

Katana 2.0v1b1 has dependencies on the following third-party libraries:

• OpenEXR 2.0.1

• OpenSSL 1.0.0.a

These libraries are provided in the Katana distribution, in separate directories under ${KATANA_HOME}/bin

An ABI-compatible copy of these libraries needs to reside on your LD_LIBRARY_PATH in order for many of Katana's

plug-ins to run. The Katana application itself uses RPATHs to locate the required libraries.

NOTE: Katana's wrapper script ${KATANA_HOME}/katana appends ${LD_LIBRARY_PATH} to ensure these

libraries are visible to Katana plug-ins.

If you manage your own LD_LIBRARY_PATH or wish to expose these libraries to plug-ins by some other

means, you can call the Katana binary directly using:

${KATANA_ROOT}/bin/katanaBin

Feature Enhancements and Important Changes for

2.0v1b1

GafferThree

A new Gaffer node type, named GafferThree, has been created to provide improved performance when dealing with

large numbers of lights in Katana projects. The GafferThree implementation takes full advantage of the new scene

graph processing library Geolib3. The existing legacy Gaffer node type from Katana 1.x is still present, and current

scenes should continue to work, but it is advised to move to using the new GafferThree node type where possible.

For more information, see the What's New in Katana 2.0 document that accompanies this release.

Graph State Variables

Node types and UI elements have been added to support the setting and querying of new, node graph-level Graph

State Variables. These can be used to control which nodes in the node graph contribute to scene graph processing at

a particular time. This can greatly simplify multi-pass/layer workflows or any other tasks that might want to re-use

node setups with different inputs or outputs.
