I’m Ayana, a Vtuber!
Today I will explain how to apply textures.
Preparation for applying texture
First,prepare an object to apply the texture. This time we will use a sphere.
Press Shift + A and select Mesh> UV Sphere.
Add modifiers to smooth the sphere.
① Open [Modifier Properties] from the [Properties] panel.
② Click [Add Modifier].
Select [Subdivision Surface] from the context menu.
A subdivision surface has been applied.
I also put on a smooth shade. Select the object, open the right-click menu in the [3D Viewport], and select [Shade Smooth ].
Smooth shade has been applied.
This time, we will apply three textures: color map, normal map, and roughness map!
Apply color map
This is the [Shader Editor]. If there is no material, click the [New] button here.
This is the default node state.
Press Shift + A to add Texture> Image Texture.
An orange node is added like this.
Click the [Open] button.
① The [Blender File View] window will open, so select a color map.
② Click [Open Image].
Connect [Color] of the image texture to [Base color] of [Principle BSDF].
The color map has been applied!
When creating a node for an image texture, you can also drag and drop it directly from Explorer like this.
Apply normal map
Next, we will apply the normal map!
Create a texture node in the same way as before, and connect [Color] of [Image Texture] to [Normal] of [Principle BSDF].
Press Shift + A to add Vector> Normal Map.
In this way, insert the added [Normal Map] node between the texture node and [Principle BSDF].
The normal map has been applied!
You can adjust the strength of unevenness from [Strength] of [Normal Map].
Finally, let’s apply the roughness map!
Roughness map is connected to [Roughness] of [Principle BSDF].
The roughness map is a black and white only image, so you need to change the Color Space to Non-Color. It’s easy to forget, so be careful!
Roughness map has been applied. You can see that the groove part that is hard to be exposed to light is darkened.
If you want to adjust the roughness, you need to insert a node for adjustment between them as in the case of [Normal map].
Press Shift + A to choose [Color]> [Invert].
Insert the nodes in between like this.
A factor of 0 means that there is roughness. The factor is closer to 0.5, the less roughness is.
This is the end of the lecture on how to apply textures.
How is everyone doing?
