File > Export Selection as Archive(s)

Opens the Export Selection as Archive(s) window, which lets you save Maya geometry in a scene file as XGen archive geometry. When you export the geometry, Maya creates archive (.xarc) and other files that contain information about geometry, its shading network, and render proxies. See Create custom archives.

Destination Folder: Lists the Collections in the scene. From the list, select the Collection that contains the Descriptions you want to save. The default locations for the archive directories are specified by the environment variables. You can edit these environment variables to change the default locations of the archives directories.

User Archives (${HOME}/xgen/archives): Saves archived geometry to the default user xgen/archives directory.

The location of this directory is specified by the ${HOME} environment variable.
Local Archives (${XGEN_ROOT}/archives): Saves archived geometry to the /archives directory.

The location of this directory is specified by the ${XGEN_ROOT} environment variable.
Global Archives (${XGEN_LOCATION}/present/archives): Saves archived geometry to the /preset/archives directory.

The location of this directory is specified by the ${XGEN_LOCATION} environment variable.
Custom: Saves the archived geometry to a user-defined location.

Archive Name: The name of the archive primitive as you want it to appear in the Archive Files list.
All of the files generated for the selected archive, including .xarc and Alembic .abc files, are saved with Archive Name as a file name.
Level of Detail: Lets you specify that low and medium resolution versions of the archive geometry are created in addition to the full resolution archive. When you add the archive as a primitive, Maya determines which version is added to locations on the surface of a mesh based on the distance from the camera. The camera distance is set using the Low Distance and Medium Distance attributes.

Disabled: Only one .abc file is create at the full resolution of the source geometry.
Automatic (PolyReduce %): Creates low and medium versions of the geometry Alembic (.abc) files based on a specified polygon reduction (as a percent) of the source geometry. These files are saved in the abc directory and have _lo and _med suffix to the archive name to identify them as low and medium versions.

Type a value beside Low and Medium to set the polygon reduction amounts for the low and medium resolution Alembic (.abc) files.
Manual (LOD Suffix): Creates low and medium versions of the geometry Alembic (.abc) files based on the object names of the selected geometry. Maya creates the source resolution Alembic from the object with the base name. By default, the low and medium resolution Alembic files are created from the objects that have _lo and _med suffix after the object base name.

You can customize the object name suffixes used to identify the low and medium resolution Alembic files. Type custom suffixes beside Low and Medium.

NoteTo create low, medium, and source resolution versions of the geometry, the base object names must be same. For example, pSphere_lo, pSphere_med, and pSphere.

Include Animation: Turn on to export animation data associated with the source geometry to the archive Alembic files.

Specify a time range for the animation by typing Start Frame and End Frame values.
