i got it, simple use wrangle node

//extract orient
matrix thuy = primintrinsic(0, “packedfulltransform”, @primnum);
@orient = quaternion(matrix3(thuy));
// get objs
string path;
getattribute(@OpInput1, path, “prim”, “path”, @ptnum, @vtxnum);
string objs = split(path, “.”);
// set instance path
s@instancefile = chs(“instance_Path”) + objs + “.obj”;

well i got it but right now i don't know how to cenvert it into an orient attribute it's a quaternion data type and the data i got it is an matrix4

import _alembic_hom_extensions as abc
node = hou.pwd()
geo = node.geometry()
# Add code to modify contents of geo.
# Use drop down menu to select examples.
abcPath = "D:/thuy_max/00_max/export/OBJ/soleil/SOLEIL_LOCATION_thuy_00_export/test.abc"
sampleTime = 1
x4_attrib = geo.addAttrib(hou.attribType.Point, "m4", ( 0.0, 0.0, 0.0, 0.0,
                                                        0.0, 0.0, 0.0, 0.0,

hi there, i want to extract a transform data from alembic file but i only can export one object, so what i want to do i want to do for all object in alembic archive. i want to use alembic transform as template point to use with copysop .. any idea?
import _alembic_hom_extensions as abc
node = hou.pwd()
geo = node.geometry()
# Add code to modify contents of geo.
# Use drop down menu to select examples.
abcPath = "D:/thuy_max/00_max/export/OBJ/soleil/SOLEIL_LOCATION_thuy_00_export/test.abc"
objectPath = "/Plane001"
sampleTime = 1
abcXform = abc.getLocalXform(abcPath, objectPath, sampleTime)
geo.addAttrib(hou.attribType.Point, 'abcXform', abcXform[0])
