Describe the bug

Hello, After I finished Hello Room,I wanted to export the furniture inside the building as a single obj, so I executed the following command：
python -m infinigen.tools.export --input_folder outputs/indoors/coarse --output_folder outputs/my_export2 -f obj -r 1024 --individual
report errors:
FileNotFoundError: [Errno 2] No such file or directory: 'outputs/my_export2/export_scene.blend/bathroom_0/0_ceiling'
In call to configurable 'export_curr_scene' (<function export_curr_scene at 0x7f3e2cdd9bd0>)

Steps to Reproduce

first I use the "python -m infinigen_examples.generate_indoors --seed 0 --task coarse --output_folder outputs/indoors/coarse -g fast_solve.gin singleroom.gin -p compose_indoors.terrain_enabled=False restrict_solving.restrict_parent_rooms=["DiningRoom"]",
and then i use the "python -m infinigen.tools.export --input_folder outputs/indoors/coarse --output_folder outputs/my_export2 -f obj -r 1024 --individual "，after that, the program reported two errors.

What version of the code were you using?

What are your FULL output logs?

The path is wrong because the filename is 'bathroom_0/0_ceiling' with a '/' in itself.

Sorry, I don't understand what you mean,and if I use "python -m infinigen.tools.export --input_folder outputs/indoors/coarse --output_folder outputs/my_export2 -f obj -r 1024", there is no error,but only one obj file of the entire house will be generated, which is not what I want

Thanks for your reply

The slashes "/" in the object names result in the errors. If you check the object names in blender, you will notice that some meshes are named "xx0/xx1/xx2". So when you export those objects individually, the save path will also be "/xx0/xx1/xx2", which means saving object "xx2" into folder "/xx0/xx1". But obviously, folder "/xx0/xx1" does not exists. You need to modify the code so that it replaces every "/" in the object names before saving them.

对象名称中的斜杠“/”会导致错误。如果您在 blender 中检查对象名称，您会注意到一些网格被命名为“xx0/xx1/xx2”。因此，当您单独导出这些对象时，保存路径也将是“/xx0/xx1/xx2”，这意味着将对象“xx2”保存到文件夹“/xx0/xx1”中。但显然，文件夹“/xx0/xx1”不存在。您需要修改代码，以便在保存对象名称之前替换它们中的每个“/”。

Thank you for your help,after I modified the following code, the code outputs the obj file normally
edit file: infinigen/tools/export.py
