Question:
Is it possible to apply Overlays on Imported Renditions in Vault?
Answer:
No, it is not possible for Vault to apply Overlays on Imported Renditions because these renditions are uploaded by the user, and not generated or processed by Vault.
Users can upload Imported Renditions of any file type, so Vault may not be able to open the file.
