This baker allows you to create a normal map from a high definition mesh.
You can bake either a Tangent Space normal map, or a World Space normal map.

Specific Parameters

Map Type: In the case of Substance Painter, a Tangent Space normal map will be baked.

Normal Orientation: The normal orientation (DirectX or OpenGL) is determined from the project settings.

Tangent and Binormal control

By default Substance Painter will use the tangent and binormals (also called bitangent) stored inside the mesh that was imported in the project.
If this information is not available (for example a file format like OBJ doesn't support it) then this information will be recomputed based on the Mikktspace tangent basis (aka Mikkt).
