La textura más simple que se puede utilizar en un objeto es una imagen sobre su superficie, sustituyendo el color liso del objeto por los correspondientes de la imagen utilizada.
To add an image to the surface of an object you will have to enter the mode of editing of materials and add textures, to do this we will have to have a window control buttons (“Buttons Window“) where you can select this option.
These new icons will define properties of the material and textures that we apply to surfaces of objects, as well as to the light projected by the color of the background of the scene or lighting systems:
The first operation to carry out will be to select the object or surface you want to that add texture. Blender performs operations on the active elements, namely, that you have selected with the right button of the mouse.
The object can have a set of previous display attributes or lack of them, in this last case we will have to define a new “material” to store the set of parameters you need blender for rendering the scene.
Along with the above buttons, the controls window is changed to show new tabs with menus corresponding to the tasks associated with working mode “Shading”.
In the absence of a material defined the first action is to add a new block of data that defines it; select the button “Add New” for this purpose.
Immediately new tabs in our window controls, that I will learn progressively:
The current tab, creation of materials, also changes, new features that are listed to appear in new items. At the moment we familiciaremos with the interface global.
The first tab that we discuss is the “Preview window“, that shows roughly how our ar object would make the render. In fact, What is shown is a simple surface, normally a sphere, to which is applied the material that we have defined:
This tab has a graphic menu consisting of a set of buttons that allow us to change the object used in the preview, como por ejemplo un plano, a bucket etc.:
The object of these options is to facilitate visually, interactively, a better approximation to the results that we obtain. The use of simple forms allows a very fast rendering and therefore a friendly interaction between complex controls with a rapid assimilation of the results to obtain.
We must emphasize that it is an approximation, Since the surrounding objects and used lighting can significantly influencing the final result.
Tab “Material” It allows you to modify the basic aspects of the surface, as its color and its opacity or “transparency”.
To analyze the effect of transparency will devote a specific article, given their complexity.
Color can mainly affect three aspects:
- Color of the object as such
- Color glitters specular highlights
- Color projected in the highlights
Each of these colors can be defined by its components in different formats (as RGB or HSV, hexadecimal format …) and also with specific windows which you enable by clicking with the mouse over the rectangles containing color in the window of Material sample.
The result of the modification can be seen in the preview window, that is automatically updated
Once modified the material we can see the end result by pressing the button F12 to render the scene
