As you may already know, textures are useful to add realism to a material. We can manage textures from the texture

tab inside the properties panel. From that panel we can create a new texture by clicking on the + button. After
21

creating a new texture, some options are displayed that let us customize how the texture looks like. The type of

We will start with normal maps. This kind of texture let us simulate rough surfaces without adding geometric

details to the mesh. We can set bump mapping in the texture tab under the Influence section. By checking the

Geometry -> Normal checkbox we let the texture be used as a reference to modify the normals of the mesh so that we

First of all we need to clarify one thing: lights in Blender are called lamps. So in all menus and option we will

To add a light to our scenes, just use the option Add -> Lamp and select one of the light type available. Let's add

In the [previous post of the series "Blender tutorial"](/2019/03/24/blender-tutorial-10-light-part-1.html) we talked about light in Blender. In this post we will continue to talk about lights in Blender.
18
+
We will start by exploring how it is possible to add a light background and setup ambient light. We can setup these
19
+
options in the world property panel. Inside it we have a section "world" in which we can modify the background of our
20
+
scene. We have some option to customize the final background result:
21
+
22
+
* blend sky, if enabled blends the horizon and zenith sky
23
+
* paper sky, if enabled with blend sky it maps the background colors to a plane
24
+
* real sky, if enabled place the horizon color in the middle (as real sky)
25
+
26
+
In the same section there's also a ambient color property. The ambient color let us manage the overall light color.
27
+
28
+
{% include blog-lazy-image.html description="blender background ambient color" src="/assets/images/posts/blender-background-ambient-color.jpg" %}
29
+
30
+
We can also choose to add a background image. To do that we have to go from the world tab directly to the texture tab. Blender will detect this operation and it will know that we are adding a texture to the background of our scene. From here we can choose the type of texture we want and we can apply it.
31
+
32
+
{% include blog-lazy-image.html description="blender background texture" src="/assets/images/posts/blender-background-texture.jpg" %}
33
+
34
+
We also have a specific type of light to simulate the sun: the sun lamp. It behaves in a similar way to the Hemi lamp. One particular feature it has is the possibility to add a sky as background and simulate a sun in terms of shape and effects.
35
+
Last but not least we have ambient occlusion. It is a technique that let us simulate more accurately the ambient
36
+
light in a scene. We can activate it from the world tab in the properties panel. It is possible to adjust how much
37
+
ambient occlusion will influence the final rendering result by adjusting the factor property. Generally speaking,
38
+
ambient occlusion is really slow in terms of rendering. Is it possible to improve the rendering speed by changing the
39
+
gather options in the world panel to "approximate "and setup the number of passes that the renderer must use.
40
+
Ambient occlusion uses the ambient color by default. If we want to achieve a more accurate result, especially if
41
+
our scene is an outdoor one, we can activate the environment light. This kind of effect will generate ambient
42
+
occlusion and eventually it will use (if we choose it) the sky/sky texture as color.

We can place cameras manually or we can use constraints. We can create a constraint by clicking the specific

constraint tab (the one with the chain as icon) in the properties panel of the camera and add a new constraint. We

can use for example a Damped Track and correlate the movement of our camera to the position of an object we select as
