Any best practice for import big files from C4D?

Hi everyone!

I’m trying to manage in UE a huge file (around 3Gb) to be imported from C4D.
Of course I can’t export nor import the file all al once… so my question: is there a best practice or a trick to manage those kind of files?

If I manually split the file into smaller ones (using layers, takes and other) then, when I import I have duplicated materials and then modifying the file in C4D and re-importing it becomes a bit tricky…

Any suggestion / documentation to share etc?

Thank you very much!
