 +===== Normal Map Types =====
 +Knald can [[the_baker_knald|bake]] both Tangent Space and Object Space Normal map data, and does so simultaneously when baking is initiated. While 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.

 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://​docs.unrealengine.com/​latest/​INT/​Support/​Builds/​ReleaseNotes/​2015/​4_7/​index.html)) & Blender. 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://​docs.unrealengine.com/​latest/​INT/​Support/​Builds/​ReleaseNotes/​2015/​4_7/​index.html)) & Blender.
