What is smoothness map?

What is smoothness map?

The smoothness parameter, shown in both Metallic & Specular shader modes. By default, without a Metallic or Specular texture map assigned, the smoothness of the material is controlled by a slider. This slider allows you to control the “microsurface detail” or smoothness across a surface.

Is smoothness the same as roughness?

Smoothness is the opposite of roughness. If you have a smoothness map you can use the “Invert” node to plug it into a roughness input.

What is roughness unity?

Smoothness and roughness are two ends of the same measure, normally using a scale of 0.0 – 1.0 . To be completely smooth, you would use a smooth value of 1.0 or a rough value of 0.0. Viewing the image, mostly black indicates zero values, while mostly white indicates one values.

What is specular map in unity?

Additionally, the alpha channel of the main texture acts as a Specular Map (sometimes called “gloss map”), defining which areas of the object are more reflective than others. A well-made Specular Map can make a huge difference in impressing the player.

Is a smoothness map a roughness map?

Roughness is the opposite of Smoothness both shaders have controls for the contribution so both works the same. The only difference is that the Standard shader has the Smoothness map packed in the Metallic Alpha, while the Roughness material has each input map separate.

How does a roughness map work?

In this map, black (0.0) represents a smooth surface and white (1.0) represents a rough surface. The roughness map is the most creative map as it allows the artist to visually define the character of a surface. It allows you to creatively tell a story about the condition of a surface.

What is a specular map?

Specular maps are black and white images in non-PBR materials that determine the shininess or reflectivity of an object in 3D. It’s used in conjunction with a diffuse and normal map to enhance the realism of the object’s texture.

What is gloss map?

The gloss map defines the smoothness, reflectivity and tightness of specular highlights. For metals, the shader doesn’t control specular color – the specular texture map does. Specular color is physically based.

What is a diffuse map?

Diffuse Maps A Diffuse map is the most common kind of texture map. It defines the color and pattern of the object. Mapping the diffuse color is like painting an image on the surface of the object. A good diffuse texture has no directional light painted in it.

How do you use a smoothness texture map?

Using a Smoothness Texture Map. In a similar way to many of the other parameters, you can assign a texture map instead of using a single slider value. This allows you greater control over the strength and colour of the specular light reflections across the surface of the material.

What is the range of smoothness in Unity?

A range of smoothness values from 0 to 1. The “microsurface detail” is not something directly visible in Unity. It is a concept used in the lighting calculations. You can, however, see the effect of this microsurface detail represented by the amount the light that is diffused as it bounces off the object.

What is the microsurface detail in Unity?

See in Glossary modes are shown above, because if you choose to use a texture map for the Metallic or Specular parameter, the smoothness values are taken from that same map. This is explained in further detail down the page. The “microsurface detail” is not something directly visible in Unity. It is a concept used in the lighting calculations.

What is smoothness and how do I use it?

The concept of Smoothness applies to both the Specular workflow and the Metallic workflow, and works in very much the same way in both. By default, without a Metallic or Specular texture map assigned, the smoothness of the material is controlled by a slider. This slider allows you to control the “microsurface detail” or smoothness across a surface.
