Does nanite decrease project size or just increase performance? Should nanite pretty much be enabled for everything at this point? Should it be enabled on mobile platform dev too? Aside from some of the unreal documents and tuts ive followed, i cant find anything that explicitly explains how to drastically reduce project size. There are a lot of vague comments here and there about reducing texture size but i cant get to the bottom of that. I have an open world and 1 small dungeon map with 5 child enemy BPs, everything as low poly/low res/low size as i can possibly get it. Its 400 MB packaged excluding unused content, and one test map. I would take any and all advice, recommended tuts, etc. Thanks in advance for any replys!
Nanite might make it worse, if anything 
It’s supposed to speed things up, nobody ever said anything about size.
Try right clicking your map and looking at ‘size map’. It can be very instructive 
Thank you! Ill leave nanite off since the packaged game seems to run on a galaxy S22 ultra. This is more a learning project since im fairly new, but id still like to be able to put it on the store for family and friends to download (at least).
All of my level assets are from quixel bridge and i only picked low quality. All of my enemies are from epic store picked ones that work with android. Ive level instanced most everything.
The size map is helpful but EVERYTHING is huge. My parent enemy is 112 mb and its not even used on the map. Just children. Just one level is 475 MB. I dont understand how 3d games can be so huge and stay uner 2 gigs. At this rate, making 10 small levels using the same assets is going to drive me up to a gig at least.
Im just not educated enough to even know where to start. If you have any suggestions, i would super appreciate it
Ive already done everything in this epic document:
Here is the size map for one level:
Yeah, welcome to optimization
The biped class needs to the parent class to exist, hence that.
I’m afraid it’s a very large topic.
As you can see, textures are a big issue ( always ). You can reduce the mip level for a lot of them, maybe. You won’t see a difference in the size map, but they package with the lower resolution.
If you want to see it changing ‘live’ in the size map, you’ll need to actually change the size of them. Then you’ll need a plugin, like
