Blender - A Crash Course in Texturing! [Abandoned House Course - Part 3]

What's up amateurs, Sharpe here and welcome back to part 3 of my Abandoned House Beginner Blender course. The name is still very long.

In the last part we've modeled this wonderful house on the journey of creating this beautiful scene of said house in the abandoned forest.

Now although the last part got a bit speedy towards the end, I did explain everything you need to know in order to

create that so hopefully you're able to follow along i'm actively answering questions

in the comment sections below but i also have a discord server where

you can share your progress and ask questions and tips we're all

very helpful and open communities so join us if you have any questions or

you want to share what you've made this part of the course however we're

gonna have a crash course on texturing because in the next part i'm gonna

teach you how to make trees and we're gonna dive into textures but

there's a few things you need to know before we get onto this so this is what this episode is for if you've been enjoying this course so far i want to ask you to drop a like, hit the bell, help me out, you know, casual YouTuber stuff.

But for now, let's focus on the actual thing. I've opened

up Blender, and if you're interested how I have an empty scene here,

you can delete everything in the scene and then drop down File, and then in default, just click Save Startup File, so this is going to be your startup file every time you open Blender.

Or you can click Load Factory Settings and go back to the way it was before. Okay, so how does texturing work?

Okay, Let's add a cube for an example and give it a material in the material properties tab. Add a new material.

I can rename it Test for example and in here I have the

information about material about the material So let's say if I give this

a red color We're not gonna see it until we

hop into viewport shading mode I like to use shortcuts

so press Z and it's down here So in the material mode you can see what the material is and in this episode I'm first gonna tell you how materials work what the inputs mean and then I'm gonna tackle UV unwrapping.

Okay, so you have all the settings of the material here, but when you're working with textures, it's easier if you open the shader editor.

So I'm going to open up this window. I'm going to open a new window here and change this into shader editor.

Okay, I'm going to press N to close this stupid sidebar. It should be off by default. I hate this. Okay, so this is the material.

I am now in version 4.0. Some parts of this have already been recorded in version 3.5 because 4.0 wasn't here before.

So I'll show you how all this works. It's slightly different, but it's pretty much the same in 3.5 and in 4.0.

A bunch of stuff just got hidden inside drop downs and it's organized a little bit differently, but it's essentially still the same thing.

There are a few main things you need to understand here. Actually, I'm going to delete this cube and I'm going to add a plane instead.

It's going to be easier to demonstrate. I'm going to scale it up and instead of adding a new material here, I'm just going to click this drop down and give it the material we already have.

So first things first, we have base color. This is the color that your object is going to use.

This is a node-based system and nodes have inputs. So you could import an image. Actually, hold on.

Let me just, let me click on one of the export folders and just bring in a texture. The rendered texture that I've already made for this.

So let's drop this in. This is our image texture and I'm going to plug it into the base color. And as you can see, it's projected on here.

It does look wonky. That's because if I hop into UV editor and edit mode, you can see this UV is stretched.

The face is square, but this is a rectangle. So we had to scale this to the same shape. It would be normal, but we'll get to that later. Let's talk about the material first.

Let's just ignore the fact that it's stretched. Go back into the shader editor. Let's talk about the inputs. What do the inputs mean?

Base color is self-explanatory. Like that's the color. One thing you have to do, this is mandatory, okay?

When you're working with textures, it's very useful to turn on Node Wrangler add-on. This is something that comes pre-installed with Blender.

It's already on your computer. So just click edit preferences and then in the add-ons section here you search for node wrangler This thing down here turn it on that's mandatory.

If you don't turn this on you are not allowed to make textures Okay, this is the law. I don't make the rules.

No, but seriously it is a it is a very useful thing I don't know why it's not on by default because everybody uses this all this does is it gives you more shortcuts So it's easier to make node magic faster.

That's all it is without this add-on you'd have to disconnect this.

With this add-on, I can just hold control and right click so I can cut this.

Anyway, I'm gonna add a UV sphere and I'm gonna give it the same test material.

I'm gonna shade this smooth so you can see. And what the metallic does is when I raise metallic value up, it's gonna shade it more like metal.

What it does is it changes the IOR, which is the index of refraction.

This works on a similar system than how actual light behaves in real life.

By raising the metallic value you're changing the index of

refraction so it's shaded like it's made of metal you can

see what it does really next up is the roughness input also a

very important one metallic works in a way that when it's zero it's not

metallic when it's one it is metallic roughness describes

the roughness of the surface for example if we take a look at my phone case and i try to angle it towards the light so you can see like it has little bumps on it right every material has microscopic bumps on it.
