MtlX Bitangent VOP node

On this page

The geometric bitangent vector associated with the currently-processed data, as defined in a specific coordinate space. This node must be of type vector3. The output RGB vector is used for tangent-space normal mapping:

Parameters

Space

The space to which the position should be transformed. You can choose from three modes. model is the local coordinate space of the geometry, before any local deformations or global transforms have been applied. object is the local coordinate space of the geometry, after local deformations have been applied,but before any global transforms. world is the global coordinate space of the geometry, after local deformations and global transforms have been applied.

Karma supports paths to an xformable prim, or a camera. Also supported are Coordinate Systems.

index

The index of the texture coordinates against which the tangent is computed. The default value is 0.
