How to package with maximum high quality settings?

I was wondering how I can package a level with the maximum possible quality?

I am ray tracing everything, and I was wondering if the regular settings I am using in my Post Process Volume are going to be used when I create a Package?
Or are there any additional settings to change the quality settings?

Thanks for any little help,
appreciate it!

ps: how can you determine the position of the entrance point - spwan? Meaning, you run the Desktop App, and when the level starts, you want to make sure the camera view spawns at a specific location… how to setup the entrance point?
