The short featured new techniques in photorealistic lighting, shading, and compositing. The Blue Umbrella: a 2013 Pixar computer-animated short film that is directed by Saschka Unseld of Pixar's technical department. !(img/maya/shading/texturing/3dpaint.png) # The bumps and folds of a sculpture are roughed in with the 3D Paint tool (a) Planar, (b) cylindrical, (c) spherical, and (d) automatic mapping of a human model. # Example of a 3D human model with the UV map. # Using different mapping methods and check the UV Texture Editor. # Create UVs for polygon surfaces (Modeling // UV /) UV texture coordinates do not have to be created for NURBS surfaces only polygon and subdivision surfaces require mapped UVs.** **NURBS surfaces have implicit UVs this means that the coordinates are built into the parameterization of the surface. **UV maps** act as a guide for the placement of images. In the **UV Texture Editor**, u-coordinates are plotted along the horizontal axis, and v-coordinates are plotted along the vertical axis.

**UV layout** is a term that refers to the 2D configuration of the UVs on a surface.

**UV mapping** refers to the process of determining these coordinates for polygon objects. ()ģD software uses u- and v-coordinates to determine how textures should be applied to 3D objects. The flattened cube net may then be textured to texture the cube. !(img/maya/Cube_Representative_UV_Unwrapping.png)Ī representation of the UV mapping of a cube. The application of a texture in the UV space related to its effect in 3D. ***Unfortunately, this power to manipulate UV is not a trivial task and can be very counterintuitive.*** > Understanding what UVs are and being able to manipulate them is incredibly powerful and allows any image to define the surface of a 3D form. > UVs are like a “where” - they are a coordinate system across the surface of polygons (think latitude and longitude across a globe). UV mapping helps with this problem: UVs are directly related to vertices on a polygon and NURBS, but the UVs cannot be manipulated in 3D space they are tied to a 2D coordinate plane and edited in a **UV editor**. There can be a problem with wrapping a 2D image (a texture) around a 3D object. UVs are 2D representations of a 3D object.

>UV stands for the horizontal (U) and vertical (V) coordinates of the 2D coordinate map space that is applied to a 3D object. Understand the processes of UV texturing and the 3D paint tool with Photoshop and know how to apply them in Maya. At the same time, the proper use of bump and displacement maps can add realism to a render. Maya's support for the **Photoshop PSD format** allows the use of layers. Using the **3D Paint tool** is an efficient way to prepare custom bitmaps. Preparing proper **UVs** for any model is a critical step in the texturing process. Although the Hypershade window provides numerous ways to prepare materials, several important techniques outside this window are important to know.
