Material Slot Order with Interchange

Development Pipeline & Plugins

When re-importing an fbx from Maya into UE the Material Slot order sometimes changes.

Before using interchange, there used to be a popup message asking about the Material Slot order change and what to do I think. I have not seen this with interchange and I do not see any options in the documentation about it.

I am calling the InterchangeManager from Python.

Is there a way I could ensure that it always keeps the original Material Slot order on re-import? Is there any other recommendation of how to ensure a consistent order with Interchange?

Thanks

Hey Claudia,

Material slot order should be preserved between reimports so it’s probably a bug on our side.

It would help us greatly if you could share the FBX file that have the issue or narrow down the repro steps.

Thank you!
