Lens too large uncompressed

Hi Carly, when importing a 2D animation, one or more sprite sheets are created. One way to reduce the size of the animation is to set the File Count parameter to a lower number on import (which represents the number of resulting animations). 

Besides file count, likely your resulting sprite sheets created in the animation tool aren't compressed. There are two ways to fix this. 

1) Reimport your animations and lower the quality which will use compression (bottom right hand corner of the animation import tool). Try to use a low number here for a smaller file size

2) You can also compress your already exported animations. To do this, go to your projects folder on your computer. There you will see a Public folder. In the Public folder, there should be another folder (named the animation name) which has your exported animation. Take all the images in there and run them through https://tinypng.com/ which will compress them quite a bit. Replace the images with the compressed ones. Your lens should now fit within the 4 mb limit

It fits within the 4 megabyte limit but still says it’s too big uncompressed which is why I’m confused

This is because there is a 20 MB uncompressed limit for the lens. To get a feeling for this, look at how big your project's Public folder is which shows you mostly how big your project is uncompressed. I'd suggest trying to run your 2d animations in the Public folder through TinyPng to get this size down quite a bit. 

This really isn't true at all. My project folder is 17 mb and my lens size is 4.4 meg, both well within the limits and it's still being rejected.

The hidden "uncompressed" limit is really bad. There's no point it telling you there's an 8 meg lens size when you can't ever get close to that limit because it hits some invisible other limit, with no indication as to how/if you can ever get beneath it.
