| - | The Derivative maps within Knald are generated on the fly from the [[height_maps_knald|Height maps]] provided by [[the_integrator_knald|The Integrator]]. They are adjustable in real time in terms of intensity via the [[the_main_tab_knald#general|Bump Scale]] slider. | ||
| - | You can also create Derivative maps quickly and efficiently from photographs, via pre-rendered Height via Knald's [[color_to_normals_knald|Color To Normals]] functionality and our world class [[the_baker_knald|baker]]. | + | [{{https://s3.amazonaws.com/docs.knaldtech.com/docuwiki/sci_fi_derivative.jpg?nolink&512|Derivative Map}}] |

| - | ===== The Derivative Maps Group's Settings ===== | ||
| - | **Flip Green:** Here you can change the axis in the dropdown to match the Normal/Derivative maps for your engine or application as required. By default Knald is set to X+Y+Z+, so if you are using a [[normal_maps_knald|Normal]] or Derivative map that differs from this configuration, you will need to change this setting. To change this setting check the Flip Green check box to save your choice. | ||

| - | **Bump Scale:** The global strength of the processed [[normal_maps_knald|Normal]] and Derivative maps. | ||
