Search Paths - Arnold for Katana

These settings specify the search paths used by KtoA to find plug-ins, procedurals, shaders, and textures.

Asset Search Path

Defines a location to search for textures and procedurals. LUTs for the tonemap imager also use this new search path.

OSL Include Path

Allows additional include search paths to be provided to OSL when compiling shaders. This option is a single string that can contain multiple search paths separated by a colon (:) or a semi-colon (;).

Plugin Search Path

Defines a location to search for plugins such as shaders, procedural plugins that create new node types, and volume plugins.

For example, if you load ass files from a different plugin, you may need to set the plugin_searchpath to load plugin-specific shaders

Here you can set folders where Arnold will look for plugins (e.g., shader libraries, custom procedural or volume binaries). These plugin binaries are .dll files on Windows, .dylib files on OSX, and .so files on Linux. Folders have to be separated with a semicolon (;) character. C4D string tokens (e.g. $prj) can be used in the search path.
