Inspector
Controls Tab
The Controls tab contains all parameters for creating the bump map.
Filter Size
This menu sets the filter size for creating the bump map. You can set the filter size at 3 x 3 pixels
or 5 x 5 pixels, thus determining the radius of the pixels sampled. The larger the size, the more
time it takes to render.
Height Source
The Height Source menu selects the channel for extracting the grayscale information.
Clamp Normal.Z
This slider clips the lower values of the blue channel in the resulting bump texture.
Wrap Mode
This menu determines how the image wraps at the borders, so the filter produces a correct
result when using seamless tiling textures.
Height Scale
The height scale menu modifies the contrast of the resulting values in the bump map.
Increasing this value yields in a more visible bump map.
Bump Map Texture Depth
This menu matches or converts the resulting bump texture into the desired bit depth.
NOTE: The below definitions are provided to clarify some of the terminology used in
the Create Bump Map node and other similar types of nodes.
 Height Map: A grayscale image containing a height value per pixel.
 Bump Map: An image containing normals stored in the RGB channels used for
modifying the existing normals (usually given in tangent space).
 Normal Map: An image containing normals stored in the RGB channels used for
replacing the existing normals (usually given in tangent or object space).
