Rendertree connecting an image to the displacement parameter

Article needs peer review

Question "Why am I not able to connect my RGB image to the Displacement parameter in the RenderTree?"

Answer Displacement in SOFTIMAGE|XSI only takes Scalar inputs ...and you have an RGB image. You need to convert your RGB image into Scalar values. </u HTMLFixup>

More Information

  1. In the Render Tree view, select Color2Scalar from the Shaders drop-down menu
  2. Connect the output of the RGB image to the input of Color2Scalar
  3. Connect the output of Color2Scalar to the input of the Displacement parameter
