We imported the avatar(.glb) and outfit(.obj) and invoked the armature
The following is the code
import bpy
bpy.ops.import_scene.gltf(filepath="D:\avatars\Aditya\avatar\nakedstand.glb", files=[{"name":"nakedstand.glb"}], import_pack_images=True,import_shading='NORMALS', loglevel=50)
bpy.ops.import_scene.obj(filepath="D:\avatars\Aditya\avatar\outfit.obj")
bpy.ops.object.add(type='ARMATURE', enter_editmode=false)
ob = bpy.context.object
amt = ob.data
referred to the link Armature Bone Global Local coordinates python scripting
did not work out am stuck how to add armature to the obj object ?
