How to find out how much memory was used to build level

I want to find out how much memory was used when building lighting and other stuff, what would I search for in the output log?

In editor: Under Window>Statistics!

The button that says “primitive stats” is actually a drop down, and there’s an option for lighting build information. Note: this only gets refreshed when you rebuild lighting, so you might have to do that, or hit a refresh button or something. I can’t remember exactly.

For more general memory stats during runtime: type “stat memory” into the console it will spit out a bunch of memory related statistics. “Pools” are the set aside available memory, so don’t be confused by those lines. Unfortunately, I don’t think they split lightmap memory from normal texture memory there though, but it gives good overall numbers during gameplay.

awesome thank you.
