What does the engine do at 93% loading?

We’re running on 4.7.3 (from the Epic P4 plus custom code) and as our project gets larger, the time it takes for the project to boot up has gone up exponentially.

Specifically, when the project loading gets to 93%, it stays there for 2-5 minutes depending on the PC specs.

What happens at 93%? I’m trying to figure out if there’s a way to reduce those loading times in any way, because while the editor is a lot more stable on 4.7 than it was on 4.6, crashes still happen and they slow us down significantly because of the boot time.

It does not seem to be linked to having a lot of assets, because I have another project that has more assets and is on the launcher version of UE4 and loads significantly faster. That project has significantly less blueprints than the main project that takes forever to load, however.

Does it compile blueprints or something at 93%?

Same problem here! Did you ever figure out what is going on? My paper2d project takes 10(!!) minutes to load.

Yeah it compiles all blueprints at 93-94% and that’s what takes a long time.

We managed to reduce the time by a good chunk by cleaning up blueprints and deleting unused ones, but there’s no real way around it. It was more of a problem a few months ago when the engine was less stable. Now that there aren’t as many crashes, the loading isn’t that problematic (or we just got used to it).

For me loading times are 99% the maps.Mind you that i have an ssd and only sprites inside my project. Everything else compiles in 4 seconds. I don’t know what to do. Every crash sets me back almost 15 minutes of staring a blank screen with a loading logo… :frowning:

Thank you for the information.
