 When viewing a texture, we also display a **normal quality indicator at the bottom as a blue-purple circle under the texture object**. The more motionless the bright dot is there, the smaller the deviation from the vertical normal is for this texture. When viewing a texture, we also display a **normal quality indicator at the bottom as a blue-purple circle under the texture object**.

 **What does a rotating point on the normal quality indicator mean?** If the bright point rotates here, then a reflection is influenced by the normal map in such a way that a rotation of the surface around the vertical axis for a light reflection causes a position shift of the reflection. This means that if the texture is to be used for a floor covering, it makes a difference to the reflection if the surface is rotated by 180 degrees. The reflection of a sun on this reflective texture is then displayed offset, which can lead to undesirable effects. **What does a rotating point on the normal quality indicator mean?** If the bright point rotates here, then a reflection is influenced by the normal map in such a way that a rotation of the surface around the vertical axis for a light reflection causes a position shift of the reflection.

 For straight surfaces such as floors or walls, only use textures where the normal quality indicator shows a point that is as stable as possible. For straight surfaces such as floors or walls, only use textures where the normal quality indicator shows a point that is as stable as possible.

 +The button ''Generate'' is used to create a normal map from the diffuse map. This button can be used if the texture doesnot have normal map or the normal map is not correct. After normal map is generated it shows the filter options with the default values in which it is generated. These values can be adjusted according to the need. On every change in the filter options new map is generated and the results can be seen on the texture sphere. 
 +
 +''Save'' button appears when we generate normal map on clicking on the ''save'' button, the newly generated normal map is saved to the textures as normal map or it replaces the existing normal map with the new map.

 Roughness map gives information and details of the surface whether it is rough or smooth. It is grayscale map and it varies in all ranges of grey shades.  Roughness map gives information and details of the surface whether it is rough or smooth. It is grayscale map and it varies in all ranges of grey shades. 
 Surface with less roughness value is more reflective and higher roughness shows lower highlights. Surface with less roughness value is more reflective and higher roughness shows lower highlights.

 +If the textures doesn't have roughness map or it needs some changes it can be generated by clicking the ''Generate'' button and can be saved using ''save'' button.
 ==== Displacement Map ==== ==== Displacement Map ====
 The displacement map, also known as the height map, defines the height range of the structure. It is also a grayscale map that varies from black to white and defines the height of the structure. The white part of the texture represents the higher part of the material and the black areas represent the lower parts. The displacement map, also known as the height map, defines the height range of the structure.
