    Unity can only create the main.obb file. If you want to create the patch.obb file, you will have to do it yourself.

    Thanks for your response! Is there a way to tie the patch obb to the apk and main obb so that assets/scenes from the patch obb can be referenced?

    I am not sure about the scenes (it wasn't tested), however patch.obb should be mounted by Unity as long as the file named with a build-id matching the value in the manifest is present. See this page and the "Note" section for a more detailed explanation https://docs.unity3d.com/Manual/android-OBBsupport.html Once the patch.obb was loaded, its contents will be available to Unity.

    Hi, sorry to jump in this old post but I have similar issue, I follow the note in the doc and add the file with the unity build-id and create the OBB with jobb but the obb seems to be corrupted. (I try to open the archive on android with some utility and I can't open it but I can open the obb created during unity build)
