The objects must have a collapsed stack and be of class poly or mesh for the script to work. NOTE: Editable meshes are considerably SLOWER to work on then editable polys.
90 Degree Tolerance: Face normals that are 90 degrees apart are considered to be a hard edge. The tolerance performs a +/- on the 90 degree angle. (i.e. tolerance of 20 = 90 +/- 20 = 70 to 110 degrees)
Set Vertex Color: Set the vertex color for vertices on hard edges to black.
Reset Vertex Colors Now: Sets the color of all vertices for the current object to white.
Selection Only: Operate on only the selected objects. When disabled will operate on all scene objects.
Progress Bar: The overall progress of the script.
Find Hard Edges: Execute the script and find hard edges.
Status: Displays the status of the script.
