You also shared this JSON report on discord:

publish-report-231213-17-56.json.json

It doesn't find any members to export:

DEBUG: Writing: []

Which is logged as empty from here: https://github.com/ynput/OpenPype/blob/2b951d29f23916e3354ecb6a328452dbf24d5282/openpype/hosts/maya/plugins/publish/extract_arnold_scene_source.py#L184

According to this it only allows nodes that are transforms with shapes. And since the nodes passed to the extract are the exact set members: https://github.com/ynput/OpenPype/blob/2b951d29f23916e3354ecb6a328452dbf24d5282/openpype/hosts/maya/plugins/publish/extract_arnold_scene_source.py#L73-L75

Make sure to put into the instance the transforms of the meshes themselves, not parent hierarchy. So no parent groups, but the direct transforms of the meshes.

I believe @tokejepsen implemented the logic - so why it behaves like that is best referred to him.

But looking at the logic I suspect if you just select the geo in the viewport and drop that into the instance that it might likely export it.

---

So instead of this:

Add the members from the group into the instance that have direct mesh shapes as children.

I believe this has been fixed since. @krishna8008 can you confirm latest AYON versions have this resolved?

[krishnaavril]

I can confirm this issue was resolved in latest AYON in Maya, Thank you @BigRoy
