Periodically tangent and binormal maps contain discontinuities (sharp changes in color between adjacent polygons), which can cause artifacts in your maps. You can edit tangents and binormals to reduce these artifacts.
To edit a tangent or binormal map
Open an explorer and expand the color at vertices (CAV) property that is storing your tangents or binormals.
Click the TangentOp2 operator icon to open its property editor.
Increase the Smoothing value to smooth out the tangent or binormal map. Keep in mind that over smoothing can also introduce artifacts, so you should increase the smoothing value in small increments.
Once you've adjusted the tangents or binormals, you can freeze them in that state. However, freezing the operator stack means that the tangent and binormal data can no longer be regenerated if for example you modify the topology of the object.
In an explorer, select the Tangents or Binormals CAV if you want to freeze the entire stack, or an individual operator under it to freeze from that point down.
