Texturing is one of the tools you can use to fully customize your shader.

2
00:00:05.000 --> 00:00:07.000
But what is a texture?

3
00:00:07.000 --> 00:00:15.000
Well, a texture is basically an image or a pattern of some sort that is used to drive a certain aspect of your shader.

4
00:00:15.000 --> 00:00:21.000
So, for example, a color texture for a wall could be the image of a plaster or brick texture,

5
00:00:21.000 --> 00:00:30.000
and that texture will be projected onto your material and can then be used in many ways to create a more interesting and detailed material for your mesh.

6
00:00:30.000 --> 00:00:37.000
So, most of the time, texturing is going to be done through images, photographs, or painted textures.

7
00:00:37.000 --> 00:00:44.000
This is the most common way to texture materials, as it allows for full customization of how your materials will look.

8
00:00:44.000 --> 00:00:49.000
We can already see how easy it is to have an image texture drive the color of our shader.

9
00:00:49.000 --> 00:00:59.000
Simply navigate to and left-click drag the file from the file browser panel into our shader editor, then connect it to the base color input.

10
00:00:59.000 --> 00:01:03.000
As you can see, the image is now projected onto our object.

11
00:01:03.000 --> 00:01:10.000
This uses the UV map of our object, which is the skinned version of our 3D object in 2D space.

12
00:01:10.000 --> 00:01:12.000
You can see some examples here.

13
00:01:12.000 --> 00:01:15.000
But we'll be going over UV mapping in another video.

14
00:01:16.000 --> 00:01:22.000
Now, keep in mind, if you want to repeat the texture over a surface, you'll find that it may look like a bunch of tiles.

15
00:01:22.000 --> 00:01:26.000
In these cases, you'll want to look for what are called seamless textures.

16
00:01:26.000 --> 00:01:33.000
Keep this in mind for things like wood floor textures, where you'll need to texture a large surface with a repeating pattern.

17
00:01:33.000 --> 00:01:44.000
Textures can also drive many other factors, including glossiness, shadows, subsurface scattering, transmission, transparency, brightness, bumpiness, and more.

18
00:01:45.000 --> 00:01:50.000
To do this, simply plug the texture into any of the input connectors of these values.

19
00:01:50.000 --> 00:02:00.000
For example, if we plug this image texture into the alpha input for our shader node, you'll notice that the texture is now affecting the transparency, or alpha, of our material.

20
00:02:00.000 --> 00:02:02.000
Except that it's not.

21
00:02:02.000 --> 00:02:11.000
Aha! That's because in Eevee, in order to use transparency in your materials, you'll want to go into the materials tab and change the blend mode settings.

22
00:02:11.000 --> 00:02:17.000
I recommend changing it to alpha-hashed, as it is the most accurate, but it does have a little bit of noise.

23
00:02:17.000 --> 00:02:20.000
Another good alternative is alpha-blend.

24
00:02:20.000 --> 00:02:26.000
Once you do that, you can see the transparency is now working, and is being driven by our image texture.

25
00:02:26.000 --> 00:02:34.000
Of course, this image is in no way made for this purpose, so for your projects, you'll want to download or create textures that fit each purpose.

26
00:02:35.000 --> 00:02:45.000
Here's an example with multiple types of textures, color map, specular map, and normal map, that are able to drive different factors to create a convincing material.

27
00:02:45.000 --> 00:02:52.000
We'll also be talking a little bit about procedural textures, also known as generated textures, in a separate video.

28
00:02:52.000 --> 00:02:58.000
Procedural textures are not image textures, but rather textures that have been generated via an algorithm.

29
00:02:58.000 --> 00:03:07.000
This allows them to have infinite resolution and variability, especially when compared to image textures, which are essentially only, what you see is what you get.
