Size of Unreal Engine

Now, I downloading Unreal Engine on Arch linux and it used about 150 GB. It’s OK, or I making something wrong?

Hey there @Vioar! Welcome to the community! So Unreal is actually quite large! But generally if your install is 150gbs you likely installed everything, including the optional parts.

Engine core is roughly 35gbs, but adding the source, editor symbols, every single build option, starter content and plugins you can reach roughly around 120 to 130 on the average windows installation. I can’t speak too directly for Linux but it’s likely around the same.

Technically, you could lose the editor symbols and every build target for anything you aren’t building to (or just add them in later), but you may end up needing the editor symbols if you crash and need to see what the error actually points to in engine. The reason they are optional is because they are so large.

An example of one of my current setup missing some of the build targets from the binary launcher:
