This page provides information about the Bezier Curve Correction texture in V-Ray for Rhino.
Overview
The Bezier Color Correction texture is one of the three available Color Correction textures along with Color Correction and Spline Color Correction. The Bezier Curve texture allows remapping any other texture color values using RGB or Luminance curve controls.
To color-correct a specific texture using a Bezier curve, simply right-click on the texture slot to bring up its context menu select Wrap In and choose Bezier Curve. This will place the existing texture within a Bezier Curve and then plug it in the original slot.
