Level instances seem to be making scene loading very slow.

I am designing a level for a village.

I’ve made each house a level instance, and I’m working on placing the house level instances in the village.

Now that I have a few dozen houses, it’s taking a very long time to open the village level, or to enter play mode from the village level.

In particular, it takes 30+ seconds to enter play mode, which is a pretty inconvenient time lag for iteratively testing and developing levels.

Is there anything I should keep in mind when creating and placing level instances?

I’m wondering if I’m doing something wrong, or if this kind of latency is inherent in Unreal Engine once the level gets to a certain size.

I’m specifically asking about using Level Instances because it would be much faster to create a level of the same size by deconstructing it all into Level Instances.
