How do i.. multiple obb?

Good afternoon, so the main game entry is max 100 MB, OBB can be up to 2 GB, my game compressed is just under 4 GB, but I can’t seem to tell Unity to split into OBB that is no larger than 2 GB in size, what am i missing? we can upload 2 OBB up to 2 GB per game and I am within that limit, if I compress my textures I can get the OBB under 2 GB but the game looks like complete trash, is there a setting in any version of Unity to say, make main apk 100mb, and split OBB into 2 files?

Unfortunately Unity does not allow to create 2 OBB files. Only a single OBB file is supported. You would have to split your assets manually and create the second file yourself.

However if you are planning to upload a new application to the Goole’s Play Store, you should be aware, that APK publishing format is not accepted for new apps since the beginning of this month: Android Developers Blog: New Android App Bundle and target API level requirements in 2021
You will have to publish using an AAB publishing format and use Play Asset Delivery to deliver additional assets. Unfortunately Play Asset Delivery is even more limited regarding the additional content size, so you might have to host some of your assets outside of the Play Store.
You can read this page Unity - Manual: Play Asset Delivery to learn about what Play Asset Delivery options Unity has.

Thanks a ton for the update, I was reading where I need to do a patch if I wanted larger than 2GB, I haven’t figured that out yet, in how the game should check for updates and download them, I was hoping at least deploy the core engine, that fits in under the 100MB limit, the levels, that is the problem. Thanks again JuliusM
