Optimizing my game. Install? Questions!! Pros welcome

As I’ve been creating assets for my game and came across many different variations of light building and loading times. I have some questions regarding loading. The more complex items I have a longer load Time of course. But as I see it takes a while to build loading… For me in the future of building items will I’ll be able to install the light build or whatever with the stage so it wouldn’t be a long load time or what? Enlighten me.

As far as i know right now you cannot save light building for particular assets or choose which ones specifically you want to build lighting for. So for now you will have to wait until it builds the lighting for all your assets.
