Exporting selected nodes only without their parents.

[Macbeth R.]

Is there a way to export selected nodes only without a top parent group above them??

For example if I have one top group/transform named ALL, then inside some other groups/transforms named FW and BG, and I only want to export BG and FG with all their children without getting the top group ALL in the resulting scene.

Greetings.

You can if you’re exporting to Alembic, it’s got a flag specifying which part you’d like to be root, but likely not other formats.

You could also unparent things prior to export, maybe with a context manager like this one.

import contextlib
from maya import cmds

@contextlib.contextmanager
def unparent(root):
    """Temporarily unparent `root`"""
    parent = cmds.listRelatives(root, parent=True)
    if parent:
        cmds.parent(root, world=True)
        yield
        cmds.parent(root, parent)

You could use it like this.

with unparent(cmds.ls(sl=True)[0]):
    cmds.file("c:/my/path.ma", exportSelected=True, type="mayaAscii")

And make it a meal-deal like this.

import contextlib
from maya import cmds

@contextlib.contextmanager
def unparent(root):
    """Temporarily unparent `root`"""
    parent = cmds.listRelatives(root, parent=True)
    if parent:
        cmds.parent(root, world=True)
        yield
        cmds.parent(root, parent)

# Retrieve an output path
filters = "Maya Files (*.ma *.mb);;Maya ASCII (*.ma);;Maya Binary (*.mb)"
path = cmds.fileDialog2(fileFilter=filters,
                        dialogStyle=2,  # Use Maya-style file dialog
                        fileMode=0)     # Any file, whether it exists or not

# Perform export, without parenthood
if not path:
    cmds.warning("Cancelled")
else:
    selection = cmds.ls(sl=True)[0]
    file_type = {"ma": "mayaAscii", "mb": "mayaBinary"}[path[0].rsplit(".")[-1]]

    with unparent(selection):
        cmds.file(path[0], exportSelected=True, type=file_type)
