Could I update things in my app without updating the app

Hello community!!

I am seeking some advice, and any and all answers will be greatly appreciated!!

I am building a mobile game for Android only at the moment, using 4.9 because I’m using gamesparks as my backend for now.

So my question, for example let’s say im building a mobile theater game. And the posters in the lobby will contain a picture. Maybe have the picture posted to a 3d widget and set on the wall. Now let’s say i want to change that picture every 15 days. Is there a way around to updating that without having the customer update the app every 15 days. Does gamesparks or unreal have a feature to where i can update certain objects without impacting the client side customer but only update the picture?
I’ve tried researching on this idea but came across nothing yet and if someone could shine some light into the right direction if there is a solution that’d be great!

Why not try using the blueprint node: “Download Image” and just updating the image on that url every 15 days? Otherwise you would need to use a plugin like “VaRest” that can read a json from your server containing all the urls

Thanks i will look into that!! You know where i could find any other information or tutorials on this?
