Control (UI) Default Value Function

Custom File Parser none Specifies the .so file with the Attributes File parser. Leave it

empty to use the default one.

Browse... N/A Brings up the file browser or your studio's asset management

browser and enables you to select the asset to use.

Set Node Name From

Path

N/A Changes the name of the node to match the filename but

without the path or extension.

Attribute Group

Name

attributeFile Specifies the name of the group attribute where the attributes

from the file are stored. When empty, the attributes are stored

directly under the location (without a group attribute).

Apply When immediate Determines when the script runs:

• immediate - the filter runs at the locations specified by the

CEL statement as they are evaluated at this node's point in the

graph.

• deferred or during katana standard resolve - the script

and its arguments are added as attributes under the

scenegraphLocationModifers group attribute. When deferred,

they are run later by the implicit

ScenegraphLocationModifierResolve filter added at render

time. When during katana standard resolve, they are

evaluated by a LookFileResolve node or by the first implicit

resolver if no LookFileResolve node is present. (They may be

tested either by enabling implicit Scene Graph resolvers in the

Scene Graph tab or with a

ScenegraphLocationModifierResolve node.)

• during material resolve - the script and its arguments are

added as attributes under the material.Scene

GraphLocationModifers group attribute. This is primarily

intended for material Scene Graph locations. The material

resolve process evaluates the script at the locations at which

the material is assign or applied. This can be useful for building

randomization or procedural control over shader parameters

at the material level without having to apply materialOverride

attributes at the geometry level.
