Bitangent

Parameter Types

Parameter descriptions

Space

The space in which the shader defines the bitangent vector. Defaults to object.

Index

The index of the texture coordinates that the node computes the tangent against. Default is 0.

Discussion

Valid values for the Space parameter include:

• model: The local coordinate space before the shader applies any local deformations or global transforms to the geometry.

• object: The local coordinate space after the shader applies local deformations, but before it applies global transforms to the geometry.

• world: The global coordinate space after the shader applies both local deformations and global transforms to the geometry.
