About Project Package Settings

Hi friends, I have a few questions for you:

  1. I have a high-dimensional game project with multiple maps and high quality mesh. I want to package my project. But there are dozens of settings in Project Settings. Can you share what adjustments I will make to package my project in the smallest and most optimized way?

  2. Do I need to build all my maps in the highest quality before packaging?

  3. I made a settings menu within the game. You can change the graphics settings according to your graphics card. But when you do this, does Compile want it after packaging?

Thanks in advanceā€¦
