Append data from other blender files (example material)

with bpy.data.libraries.load(MATERIAL_LIBRARY_FILE) as (data_from, data_to):
    data_to.materials = data_from.materials

for mat in templateMat:
    materialList.append(mat.name)

remove all materials

import bpy
for material in bpy.data.materials:
    material.user_clear()
    bpy.data.materials.remove(material)

generate meshes from MeshCacheSequence

import bpy

    for i in range(1, 30):
        if i % SKIP_RATE != 0:

clear morph frames

    for obj in bpy.data.objects:
        if obj.get('is_frame'):
            bpy.data.objects.remove(obj)    

Assign mesh sequence cache

def assign_abc(obj):
    for child in obj.children:
        child.modifiers.clear()

                mod.object_path = path.path
