I would like to know how I am able to use an image I created in 3d style as an actual 3d object in my game?
This is an image that best portrays my will: http://www.free2play.com/img/restaurant-city-screenshot-2.jpg
As you can see, these are all 2d objects drawn on an external program, but brought into the engine as 3d objects in a 3d world.
Any tips on how I can accomplish that?
Unfortunately, it’s impossible. Those need to be reworked piece by piece as separate 3D objects.
Is this specifically impossible with Unreal Engine or entirely?
That’s the case with all engines and all software out there. At the moment there is no present technology capable of auto-converting 2D images into 3D models. It might be somewhat possible in few years.
What you need to do is design the room in 3D software (Blender, Sketchup, 3ds Max,…) and then import it into Unreal Engine. After that, you might use Orthographic camera and post-processing in order to get the desired art-style.
There is at least one hacky method to do this. Make an svg image in inkscape. Import into blender, convert to a mesh and export as an obj or whatever… There are some problems with this and you’ll have to experiment, but it has a pretty decent outcome.
