Vertex Colors Group

When on, ProOptimizer preserves vertex color data. When off, ProOptimizer discards vertex colors. Default=Off

This control is unavailable if the object has no vertex color data.

This control is available only when Keep Vertex Colors is turned on. When on, ProOptimizer preserves boundaries between vertex colors. When off, ProOptimizer disregards vertex color boundaries. Default=off.

• Tolerance This is available only when Keep VC Boundaries is turned on. The Tolerance value controls how vertex color boundaries are treated. A value of 0 (the default), preserves all vertices that have a color that differs from a neighboring vertex. A value of 255 allows any vertex to be removed, even if its neighbor has a different vertex color.
  Tip: A tolerance of 20 preserves most color boundaries, but also allows a reasonable amount of optimization.
  

  Original object

  Vertex colors make the object appear illuminated

  

  Keep Vertex Colors turned off

  ProOptimizer shows the object’s two materials, but vertex color is lost.

  

  Keep Vertex Color turned on

  Tolerance = 0

  Frozen points are shown in red. Almost all faces are frozen and not optimized, because each point has a color that differs from its neighbor.

  

  Keep Vertex Color turned on

  Tolerance = 35

  Frozen points are shown in red. Only the center, which has important color variations, is frozen.

  

  Keep Vertex Color turned on

  Tolerance = 90

  Frozen points are shown in red. Only the frontier between the two materials is frozen.
