How to reduce build size by using DLCs SDK ? (Unity SDK)

Question

Hello folks,

I’m a software engineer working on a new unannounced game. As we are currently planning our integration, I have some questions about DLCs.

 

Plateforme: Unity 2021.3.41f1

Target device: Android & IOS

Problematic: We need to reduce our build size for the first download of the game.

 

What we have in mind (and it’s maybe wrong) is to pack our first build with all events (or most) pointing to “empty/silence” sounds. Which would looks like this

 

Included in the build:

• SoundBank
  • Working unit
    • FXContainer
      • Sound_Shotgun_Fire

 

DLC #1:

• SoundBank
  • Working unit
    • VoicelinesContainer
      • NewSound_Hello_World
    • FXContainer
      • Sound_Shotgun_Fire

 

It would work as follows:

• The DLC adds new sounds, events, and all related assets via new containers, etc.
• The DLC will override some containers (like voicelines in this example) by replacing all sounds that are "silenced" in the original container.

 

Another solution would be to have an almost blank soundbank in the main build and then load DLC packages depending on the user's needs:

• DLC #1: All FX for season 1
• DLC #2: All voicelines for season 1
• ...

What would be your suggestions?

 

Best regards.
