ATTN: Note on Updating Games
* This page address a common issue with seeing an increased uncompressed build size when updating your game's game engine version.
When you update your game with a newer game engine version (ex: moving from Unity 2019 to Unity 2022), you experience an "issue" with your uncompressed build size increasing past the 30 MB limit. In these instances, you need to look at your uncompressed <GameDirectory>/Build
in that folder, next to the index.html file. Your compressed build files will have .gz
or .br
extension depending on the compression used.
This is different from your zip'd folder for LoL submission. The size of the zip'd uploaded file is not checked.
Updating Unity to the latest LTS is going to include different, and possibly, larger packages into your game. (Json.Net over previous built in unity json, etc). The increased size is NOT from the updated SDK, the code in there is very small.
Unity may include different packages in different engine versions, so you need to look at the build output to see what is included and optimize it accordingly. Final build compression size does not matter, nor does the zip upload file size for submission.
You should check all the normal optimization build settings:
Code stripping high
Build for small size
Go through the packages and make sure they're not including a large package (Ex: Physics when your game uses 2d physics, etc)
Look at your build output log using a tool or just in a text editor to see the size of the assets included in the build
You may need to reduce your texture size, meshes compression, animation quality, audio quality, etc.
Side note: we've noticed some older games that had gzip compressed build files before we fully supported this, which means they were able to upload games that, when uncompressed, where larger than 30 MB. If this was you, you'll have issues trying to re-upload your game without optimization. The difference in your uncompressed build from early Unity to now should be close to the 30 MB limit, ~ 2-5 MB. Which can hopefully be optimized with just a few settings.
Brolti is a very optimized compression so don't be surprised if your compressed build is much smaller, i.e. 1/3 - 1/4 of your uncompressed.
