Bump/Sharp Emboss

 

 

A monochrome relief texture is rendered by the Sharp Emboss function. The light source is always located in the upper-left corner of the texture.

The Heightmap contains the relief data, which is needed to calculate the emboss effect. If you keep applying the function to the same texture with a high Pre-Smoothing (and Amplify) value, you can create a sand stripe pattern like visible in Image 3.

Regulate the contrast of the new texture with the Amplify value.

The new surface color is the Primary Color.
