Secondary Rays

Amount of rays emitted to read the nearby geometry. A high value will produce less noise but take longer to compute. Default is 32.

Sampling Radius

How far the nearby geometry is taken into account to compute the curvature at the surface of the geometry. High values may produce stronger edges while lower values may produce thinner edges but miss information.

Relative To Bounding Box

Defines if the sampling radius is relative to the size of the mesh or if it defined as a unit based distance.

Self Intersection

Matching by name of curvature rays. Indicates how the bakers should match low and high-poly geometry. It can be used to filter the baking process without the need to manually move apart (explode) meshes.

Possible values:

• Always (default): Low-poly mesh is matched with every high-poly meshes.
• By Mesh Name: Filter the meshes by their name to avoid matching with unwanted geometry.

To learn more about matching geometry see: Matching by Name.

Automatic Tonemapping bounds

Controls how the curvature values should be wrote into the texture. If enabled, the range of value will be normalized between 0 and 1 based on the minimum and maximum value found during the baking process. If disabled, the minimum and maximum value are defined manually.

Tonemapping Min

If Automatic Tonemapping bounds is disabled, defines the minimum value to scale the curvature result to fit into the texture.

Tonemapping Max

If Automatic Tonemapping bounds is disabled, defines the maximum value to scale the curvature result to fit into the texture.

Normal Map

Optional path to a normal texture. Can be used to replace the internal computation of the baker.

World Space

If enabled, the normal texture is interpreted as a World Space normal instead of a Tangent Space.

Normal Orientation

Format of the Normal texture if in Tangent Space.

Possible values:

• DirectX (default)
• OpenGL
