(I work on windows 10, blender LTS 2.93.8)
custom options ARE working for my needs, you just need to change two flags:
use_blen_objects=False, group_by_object=True
(on the beginning I was only setting “group_by_object” to True but first it needs to “use_blen_objects” set to be false)
problems:
- Because “group_by_object” it is my default way of saving obj in blender (due to better naming in Unity) I was trying to edit blendlib.py. I made it by unpacking zip with addon, editing this part of a file:
after this I repack blendlib.py to zip, uninstalled addon, installed it again and exporting wasn’t working as expected.
I’m not 100% sure it was not a mistake on my side, but quite sure. If you can check on this, it will be lovely.
- I think it is not the best UI here:

In my opinion “Use object’s name” checkbox is not needed. In fact it takes me some time to figure it out and uncheck it. But I understand that UI can be fixed forever.
And for unity users, why they should use “group_by_object=True”
In unity project search you search meshes not by file name, but mesh name, and default method of exporting leave you with a lot of meshes named “default”. It is better when they got proper names.
There is one catch: object and mesh should be named the same, in other way in unity you will have name that is a merge ot object and mesh name
so this hierarchy:

will end up in unity as “Room Bakedlight_cube”
but this:

will be just “Room Bakedlight”
I’m terribly sorry for not very good english. I will try to correct this later, but I hope its clear, even if not gramatically correct. I will answer any addtional questions.
