BumpMapGenerator is, as the name suggests, a tool with which you can create your own NormalMaps or BumpMaps. Starting from a normal ColorMap or HeightMap you can create your desired BumMap with the help of various filters and generators. The user interface and usability is designed for the more experienced users, but even with little experience and only a few tutorials on the topic you should be able to do your first steps. The tool is completely freeware and it is as good as it’s commercial competitors, such as ShaderMap 2 or CrazyBump.

Below is a list of all objects that are available in the tool to generate a normal map:

• Textures are used primarily as a source for other objects and can be loaded from *.bmp and *.tga files. There are four different types of texture:
  • RGB – represents a texture with red, green and blue values
  • RGBA – represents a texture with red, green, blue and alpha values
  • Luminance – represents a texture with gray values. This type of texture is best suited for HeightMaps
  • LuminanceAlpha – represents a texture with gray and alpha values
• Filters are objects that affect the color values of an existing object. The texture type does not change. In each filter you can setup which color channel will be affected by the filter. There are three filters:
  • Hue / Saturation – with this filter you can adjust the hue and saturation of an object
  • Brightness / Contrast – this filter affects the brightness and contrast of an object
  • Levels – using this filter, the color levels ​​of an object can be manipulated
• Generators can be used to generate new objects. The texture type of the source object might change. There are seven generators:
  • Monochromatic – converts any object into a greyscaled object. The weight of the single color channels can be adjusted freely. The resulting format is Luminance or LuminanceAlpha.
  • Noise Detection – recognizes the noise around a certain Texel. The higher the difference of the surrounding texels, the higher the value of the calculated texel. The format of the object does not change.
  • Blur – provides several ways to blur an object. The format of the object will not be changed.
  • Blend – combines different objects with blending. The blend factors can be set individually for each object. The format is determined by the first source object.
  • Merge – connects two objects together. You can select which color channel to be used from which object. Again, the format is determined by the first source object.
  • NormalMap – generates a NormalMap or BumpMap. The format is RGB.
  • NormalMapMerge – connects multiple NormalMaps together. The intensity of the normal maps can be set individually for each object. The resulting format is RGB again.
• 3D-Preview provides a three-dimensional preview. The textures can be viewed on various preset objects, or a mesh loaded from an wavefront *.obj file.
