Scale


This parameter contains a scaling factor whose default value is 100%.  When the scaling factor is 100%, then the size of the texture  unit retains the dimensions specified in the Texture Map Controls dialog.  When a factor other than 100% is used, the unit is scaled up or down accordingly.

The practical implication of the unit sizing parameters is that, if the unit is scaled up, a larger texture will be generated, and if it is scaled down, a smaller texture will be generated.  

Using shaders from different categories with different scales allows you to superimpose patterns at different sizes.

 

For example: a Brick pattern at 100% and a Rough bump pattern at 50% may be combined on a single surface
