I figured this would be the best section to post this in.
I’ve been struggling for a couple days now with a rather frustrating problem. I’m working on a very simple visualization for a client in 4.13 that uses about 5MB of data and has one very basic blueprint in it. However, after packaging the file, the package is more than 200MB’s.
To isolate the possibility of having made heavy assets, I created an empty project without starter content in it and removed everything from the default level. Still, when packaging the empty project it was a massive 170MB’s.
I spent three days now looking for ways to reduce this. I checked all the correct boxes, disabled all plugins, read all the documentation about package sizes and spent ages reading topics about this. Unfortunately none provided a solid answer on how to reduce this without requiring you to posses a comprehensive skillset in C++ to rewrite some core programming of the engine, which I simply can’t. Hence I’m using blueprints.
Eventually I managed to shrink it down to about 115MB, but it’s still way too large for an empty project. Especially considering the Tappy Chicken game is only about 15MB. I want to use this engine to send interactive concepts to a client. There’s no client in the world who’d want to bother hauling in several hundreds of MB’s for each and every little tweak there has been made. Especially if they want to view it on their phone. 200MB is simply not done.
After some digging I noticed that by default all of the engine’s content seems to be packed together with the game. The cooking log mentions files being cooked such as primitive objects, VR assets, materials and even tutorial files! I can only imagine that this is the culprit but I have no clue on how to prevent these unnecessary assets from packaging. You can only exclude folders from within the project’s own content folder. With the little documentation around about this, I’m pretty much begging anyone to ask if they have a way to fix this. I simply don’t understand why these assets are all packed in the first place. Especially the tutorial files.
Any help is really appreciated.
