Both!
The textures that my assets are using are 20MB per single file at least. Multiply by 3 (at least) per asset (normals texture, the _D, plus another) times a gazillion assets (lol).... I've dumped everything I'm not using. The packaged project is over 2GB. Can I still upload to itch.io? I'm getting rid of some very heavy foliage assets and replacing with some really low rez ones, but I have an entire interior scene from the dungeon asset pack and its textures are 1.5GB....
I'm trying this setting when UE4 cooks the project with compression enabled. Hopefully that might be better.
But back to itch.io, what's their limit?
Thanks for taking the time to reply! I'll check out your game
