As stated before, after obtaining the objects through the
modeling and sculpting processes, the rendering can begin.
Through this rendering process, a 3D object that has been
created can be placed in a virtual space. For this setting to
achieve a realistic look, lights of different types will be
added, which will illuminate both the object and the scene.
One can see the differences between Figures 12 and 13, in
which two distinct render engines have been used.
Finally, this model can be applied to an example created for
a previous congress [4]. This new object can be used and
imported into a complex 3D or rendering software, so that, by
means of simple parameters, it can be incorporated into a
realistic atmosphere. Through this technique, basic shapes that
had been previously created have been used to define
complex volumes in a matter of minutes.
This allows for the efficient design and exploration of new
forms that can be offered to customers as a preview, like that
shown in Figure 14.
In Figure 12, the rendering engine that has been used is the
one incorporated in ZBrush by default. It gives a realistic and
appealing texture, to which you can adjust both the
parameters of lights and quality of the shadows as well as the
end result. In addition, it allows to create the final render
within the same program. The main disadvantage compared
to other more specialized rendering engines is that it does not
offer the same control over the lights and their position in the
world. The parameters with which one can experiment are
smaller than a professional render engine such as "Arnold",
"Keyshot" or "Vray".

In Figure 13, the result has been obtained through the specific
"Arnold" engine, which is integrated into the 3DS Max
modeling software program. In order to do this, it has been
necessary to export the ship previously modeled in ZBrush to
the 3DS Max program as an object of type "OBJ", a process
that allows one to continue working with the object modeled in
3DS Max. By incorporating natural daylight lighting within the
environment, and adding some lights to the object itself, the
result is a more realistic-looking scene.

Painting" in Adobe Photoshop.
2. C ONCLUSIONS
As mentioned in the introduction, the most advanced software
allows to create designs of complex shapes in a simple way.
This allows to save costs to create preview images in the early
stages of scenario and environment design.
For this, one can resort to ZBrush, a software designed for the
film and video game industry, but that can actually be used in
architectural work processes and building engineering.
Through an organizational process known as "Kitbashing", the
