pymel.core.system.selLoadSettings

selLoadSettings(*args, **kwargs)

This command is used to edit and query information about the implicit load settings. Currently this is primarily intended for internal use within the Preload Reference Editor. selLoadSettings acts on load setting IDs. When implict load settings are built for a target scene, there will be one load setting for each reference in the target scene. Each load setting has a numerical ID which is its index in a pre-order traversal of the target reference hierarchy (with the root scenefile being assigned an ID of 0). Although the IDs are numerical they must be passed to the command as string array. Example: Given the scene: a / b c / d e where: a references b and c c references d and e the IDs will be as follows: a = 0 b = 1 c = 2 d = 3 e = 4 selLoadSettings can be used to change the load state of a reference: whether it will be loaded or unloaded (deferred) when the target scene is opened. Note: selLoadSettings can accept multiple command parameters, but the order must be selected carefully such that no reference is set to the loaded state while its parent is in the unlaoded state. Given the scene: a | b [-] | c [-] where: a references b b references c a = 0 b = 1 c = 2 and b and c are currently in the unloaded state. The following command will succeed and change both b and c to the loaded state: selLoadSettings -e -deferReference 0 “1” “2”; whereas the following command will fail and leave both b and c in the unloaded state: selLoadSettings -e -deferReference 0 “2” “1”; Bear in mind that the following command will also change both b and c to the loaded state: selLoadSettings -e -deferReference 0 “1”; This is because setting a reference to the loaded state automatically sets all child references to the loaded state as well. And vice versa, setting a reference the the unloaded state automatically sets all child reference to the unloaded state.

Flags:

Long name (short name)		Argument Types	Properties
activeProxy (ap)		unicode
	Change or query the active proxy of a proxy set. In query mode, returns the proxyTag of the active proxy; in edit mode, finds the proxy in the proxySet with the given tag and makes it the active proxy.
asURI (au)		bool
	When used with a main query flag and the unresolvedName flag it indicates that the file names of all reference files returned will be URI. This URI may contain environment variables and may not exist on disk. If this flag is not present, the OS native file path will be returned.
deferReference (dr)		bool
	Change or query the load state of a reference.
fileName (fn)		unicode
	Return the file name reference file(s) associated with the indicated load setting(s).
numSettings (ns)		int
	Return the number of settings in the group of implicit load settings. This is equivalent to number of references in the scene plus 1.Flag can appear in Create mode of commandFlag can have multiple arguments, passed either as a tuple or a list.
proxyManager (pm)		unicode
	Return the name(s) of the proxy manager(s) associated with the indicated load setting(s).
proxySetFiles (psf)		unicode
	Return the name(s) of the proxy(ies) available in the proxy set associated with the indicated load setting(s).
proxySetTags (pst)		unicode
	Return the name(s) of the proxy tag(s) available in the proxy set associated with the indicated load setting(s).
proxyTag (pt)		unicode
	Return the name(s) of the proxy tag(s) associated with the indicated load setting(s).
referenceNode (rfn)		unicode
	Return the name(s) of the reference node(s) associated with the indicated load setting(s).
shortName (shn)		bool
	Formats the return value of the ‘fileName’ query flag to only return the short name(s) of the reference file(s).
unresolvedName (un)		bool
	Formats the return value of the ‘fileName’ query flag to return the unresolved name(s) of the reference file(s). The unresolved file name is the file name used when the reference was created, whether or not that file actually exists on disk. When Maya encounters a file name which does not exist on disk it attempts to resolve the name by looking for the file in a number of other locations. By default the ‘fileName’ flag will return this resolved value.

Derived from mel command maya.cmds.selLoadSettings

Example:

import pymel.core as pm

import maya.cmds as cmds

# Given the scene:
#
#
#        a [+]
#       /     \
#      b [-]   c [+]
#             /     \
#            d [-]   e [+]
#
# With the IDs:
#    a = 0
#    b = 1
#    c = 2
#    d = 3
#    e = 4
# set c, d, and e to the unloaded state
pm.selLoadSettings( '2', '3', '4', e=True, deferReference=1 )
# this will also set c, d, and e to the unloaded state
pm.selLoadSettings( '2', e=True, deferReference=1 )
# set b to the loaded state
pm.selLoadSettings( '1', e=True, deferReference=0 )
# set b and d to the loaded state
pm.selLoadSettings( '1', '3', e=True, deferReference=0 )
