How do you package a project that can be deployed to the Steam store?
That’s a pretty broad question. Have you managed to package your game at all? Is it just the deploying to the steam store that you need help with? Have you got your steam app set up? Have you been through the GreenLight process etc?
p.s. I noticed you asked the exact same question twice, which is frowned upon. Maybe add some more information about where you are up to in the process and which part you are stuck on at the moment would yield some replies.
I can and have packaged my game. What I don’t understand is deploying to the steam store.
You just include the steamwrks in your code in your build. Search for steamworks in ue4, there are good tutorials on this. It would be too long to explain here.
