Just found a recent good article on [Getting Real-World Objects into Unity 3D][1] that adds a different and good prespective using [MeshRoom][2] and [MeshMixer][3].

The following image shows the three steps required to achieve it

[![Getting Real-World Objects into Unity 3D][4]][4]

> 1. Take several photos, as many as possible, around the object and use MeshRoom to digitize it. [This tutorial illustrates the process][5].
> Upon saving Meshroom's own files the program also creates a folder
> named "MeshroomCache" (\MeshroomCache\Texturing) where it deposits the
> result in the widely exportable .obj format.
> 2. The digitized object will probably need some cleaning (parasite shapes of the surroundings) and/or reshaping. That's easily done with
> MeshMixer. Since digitized objects tend to be highly detailed and
> heavy on rendering, we may need to reduce/simplify the
> complexity/detail of the model, a feature included in MeshMixer. this
> program also exports to .obj format (among others). Look at [Meshmixer
> Quick Tips tutorials][6].
> 3. Finally drag the .obj with the associated textures into a Unity 3D project. It's a straight standard process [explained in Unity's manual][7].
