I want to add some extra information into the exists abc file or if its possible while creating alembic cache with some extra information in maya or any cg application using pyhon. I am appreciate any one can help me to edit the alembic file.
input example
meta_data = {'name': 'Hero', 'tag': 'test_show'}
abc_file = '/show/test_show/scene/hero.abc'
from alembic import Abc
from alembic import Abc
archive = Abc.IArchive(abc_file)
top = archive.getTop()
meta_data = top.getMetaData()
print meta_data__str()
You can't write just arbitrary data but you can set description and application strings:
from alembic import Abc
MY_APP = 'My cool application'
def write(abc_file, description):
archive = Abc.CreateArchiveWithInfo(abc_file, MY_APP, description)
def read(abc_file):
archive = Abc.IArchive(abc_file)
top = archive.getTop()
return Abc.GetArchiveInfo(archive)
abc_file = 'alembic.abc'
write(abc_file, 'An abc file cool description')
archive_info = read(abc_file)
print(archive_info.get('appName'))
print(archive_info.get('userDescription'))
print(archive_info.get('whenWritten'))
