The following code shows how to export file to memory, includes the dependent file by using MemoryFileSystem.
from aspose.threed import FileFormat, Scene
from aspose.threed.entities import Box
from aspose.threed.shading import LambertMaterial
from aspose.threed.utilities import MemoryFileSystem
from io import BytesIO
# create a scene with material
scene = Scene()
scene.root_node.create_child_node(Box()).material = LambertMaterial()
# create a save option and specify the file system, so the dependent file will be written to memory
opt = FileFormat.WAVEFRONT_OBJ.create_save_options()
mfs = MemoryFileSystem()
opt.file_system = mfs
# obj's material file name is associated with the obj's file name, so we need a explicit name.
opt.file_name = "test.obj"
with BytesIO() as ms:
scene.save(ms, opt)
# the test.obj was written to variable ms, and we can also get the test.mtl file content by
materialFile = mfs.get_file_content("test.mtl")
