![]() ![]() In order to produce quality objects, you need to use specialised textures which may look odd but add subtlety and richness and enhance the realism of your work. Unfortunately, this will probably not yield optimal results. You’d think that you can simply place the texture on the model and be done with it. the 3D monochrome model with no textures, animation, or effects, and its UV mapping. If you add a new geometry: Textures with Varied Effects The following two examples illustrate the importance of doing things in the right order. Your decision about whether to use automated mapping will depend on which technique you plan to use to create textures.Īnother important point is that the UV mapping process can only be started after the 3D modelling is done, and, due to technical limitations, before any form of animation. On the other hand, textures generated in 2D applications such as Photoshop require manually-optimised mapping. Newer automated models allow the artist to paint directly on the model, doing away with UVs entirely. However, they must be handled with care, as the seams often end up being in places that, though acceptable, are visible. Their quality has steadily increased and they are now up to a professional standard. Ideally, the seams will be invisible, since they should be located on a cut or edge of your model (for example, the seams on a pair of pants, or the joint between two metal plates), or where the user won’t notice them (for example, if your model is a person, under the arms, at the back of the head, under hair or a hat).Ī few years ago, we saw the advent of automated UV-generating models giving the user varying levels of control over the process. As a general rule, it is best to keep the number of seams to a minimum, since the most labour-intensive part of the process is optimizing their number and position on the model. This example clearly shows how the model is unfolded in a single piece onto a 2D canvas. Let’s look at what mapping looks like, using the common example of a simple cube: Other processes exist to color models, but they have much narrower limitations. This process makes it possible to produce models rich in color and detail. Once the mapping is complete, the artist can produce a custom image based on the “pattern” and apply it to the 3D model. The 3D model is unfolded at the seams and laid out flat on a 2D plan, not unlike the process used for pattern-making in sewing. The term “UV” refers to the bidimensional (2D) nature of the process: the letters “U” and “V” denote the axes of the 2D texture because “X”, “Y” and “Z” are already used to denote the axes of the 3D model. ![]() UV mapping is the 3D modeling process of projecting a 2D image onto a 3D model’s surface. In this article, we’ll examine UV mapping techniques and the different types of textures. ![]()
