 ====== Normal Maps ====== ====== Normal Maps ======
-The Normal 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 Normal 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]]. 
-Please see the [[color_to_normals_knald|Color To Normals]] & [[the_baker_knald|The Baker]] pages for more information.

-===== The Normal 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 or [[derivative_maps_knald|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. 
-**View OS Normal:** Enables the viewing of the Object Space Normal map in the Normal tab rather than the default Tangent Space Normal map. 
-**Bump Scale:** The global strength of the processed Normal and [[derivative_maps_knald|Derivative]] maps.

-===== Normal ​Map Types ===== +The Normal ​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 in the [[the_main_tab_knald|Main Tab]].
-Knald can [[the_baker_knald|bake]] both Tangent Space and Object Space Normal map data, and does so simultaneously when baking is initiatedWhile both maps can be used for real-time rendering, Tangent Space is by far the most commonly used during runtime with Object Space maps tending to be used more for texturing purposes (channel data for selection masks etc.) than when they were first introduced. +

-===== Tangent Basis ===== +
-Knald uses MikkTSpace by Morten S. Mikkelsen, which is available for free, from [[http://​​index.php/​Dev:​Shading/​Tangent_Space_Normal_Maps]] the [[http://​​Developers.aspx|xNormal SDK]]+
- +
-It also calculates the bitangent on the fly by default due to the fact that it is more efficient on modern hardware (sending data from vertex to pixel shader is more costly than executing a minor calculation in the pixel shader), which is consistent with Unreal Engine 4((As of release 4.7 https://​​latest/​INT/​Support/​Builds/​ReleaseNotes/​2015/​4_7/​index.html)) & Blender.+
 +You can also create Normal maps quickly and efficiently from photographs or pre-rendered Height via Knald'​s [[color_to_normals_knald|Color To Normals]] functionality.
 +Please see the [[color_to_normals_knald|Color To Normals]] page for more information.
