Create Arnold procedurals suitable for invoking Autodesk XGen (bundled with Maya). If you wish to use camera-guided data (such as LOD), feed the scene with a camera to the input. This node is influenced by the following environment variables:

MAYA_PATH: root of Maya installation.

MTOA_PATH: root of MtoA installation.

XGEN_LOCATION: xgen location within Maya, usually ${MAYA_PATH}/plug-ins/xgen. 

 

location

Path to Maya installation to find XGen libraries (optional).  If empty, KtoA will use the MAYA_PATH environment variable to locate Maya.

paths

Whether to customize paths to Maya/MtoA/XGen, or just use MAYA_PATH, MTOA_PATH, and XGEN_LOCATION environment variables.

specification

How to find the XGen data: either directly specify a .xgen file, or else specify a Maya project directory and the .xgen files will be searched for.

xgen File

Path to .xgen file (required).

Description

XGen description to render.  If left empty, descriptions will be found from the XGen data.

Patches

name_scheme

Naming scheme for child locations of unique XGen procedurals.  It honors the following tags (enclosed in angle braces): scene, collection, description, patch.

xgen_shader

Default shader to apply to procedural contents, except for archive parts that have their own material assigned. If you assign a material to the location normally (via MaterialAssign), it will override what you set here on xgen_shader.

camera

The camera used for LOD and other effects; can be blank to disable camera-related effects.

fps

Frames per second animation is proceeding at; 24, 30, 48 and 60 are typical.

Samples

min_pixel_width

mode

verbose

Log level for XGen.
