Bump
In the Bump tab, the parameter Depth adjusts the depth of the unevenness encoded in the Bump Map. It is a surface state roughness, i.e. not very deep. From a geometrical viewpoint, the surface is not altered and remains perfectly smooth.
The Reflection parameter adjusts the depth of the hollows and bumps encoded in the Bump Map.
In the accordion menu Bump Map, click the None button to load the texture which will serve as a reference for the bump or the glossiness of the material.
In the accordion menu you will find Projection :
Notice
The Allow repeat on U and Allow repeat on V parameters allow you to repeat the texture on U and/or V.
By checking the Mirrored checkbox you can reflect the texture in U and/or V.
