Wrapped Bump Map
SHADER TYPE: Wrapped Bump Map
Wrapped Bump Map is a displacement type where the bump map of a surface is created from a given image file. The dark parts of an image are lower on the surface, and the light parts are higher. The image file is usually duplicated several times on the surface, so particular attention must be paid to the continuity at the edges of the image.
| Parameter: | Explanation: | Default value: | Possible values and comments: |
| File Name | Name of the image file | "" | jpg, tiff, targa, bmp, lwi files: as a default, the program searches for the file in the lw directory. |
| Amplitude | Maximum height factor of the roughness | The higher the value, the more the differences in height are emphasised. Values below zero will cause the bump map to invert, i.e. the low areas rise and vice versa. |
