VPK Support in UE4

Is there any way that i can modify the engine to package game data into a vpk file (Used for steampipe), instead of using a pak file?

Hello,

This is not something that we support. It is something that you would have to spend time implementing on your own. However, there is a plugin that would allow you to import content from Hammer into Unreal, but it has not yet been accepted on the marketplace. The forum post below provides a couple of alternative links that you can use to get the plugin if that would be something you’re interested in.

Have a great day
