Is there a way to know the end of loading when running the game?

[Kong]

I'm making a game, and I was planning to use CityEngine's example "NYC2259".

And When I open the map, there are certain time to load the city. (Image below) 

And also this loading is happening when I run the game too.

So when I run the game, my character is falls. But I wanted my character standing on the top of the left building like below image.

(This image is captured before running the game.)

So I want to spawn the character when this loading is end.

Is there a function or variable to know that?

If there's no way to solve this, I was planning to delay time enough and spawn my character.

This is a game engine question not CityEngine. You need to look at collisions for your static meshes inside the game engine and possibly delay the character spawn. What game engine are you using?
