Unity Asset - DestroyIt Destruction System v1.3.4[AKD][CTRC]

Notes:To fix the Crease Shading error....

Main file that comes with the download looks like this:
-----------------------------------------------------------
namespace UnityStandardAssets.ImageEffects
{
[CustomEditor(typeof (CreaseShading))]
public class CreaseShadingEditor : Editor
{

I corrected it by changing CreaseShading to CreaseShadingEditor on both lines, this seems to be what it's looking for as if you change it to some other random title a new error appears not recognising it.
-----------------------------------------------------------
namespace UnityStandardAssets.ImageEffects
{
[CustomEditor(typeof (CreaseShadingEditor))]
public class CreaseShadingEditor : Editor
{


Near as I can tell this is version 1.3.4 it all works fine once you fix the script error above and fix the shader errors

you'll get a bunch of shader errors (purple shaders) change them as needed to legacy bump diffuse etc....some objects in the demo wanted destroyit legacy bump diffuse.I found them all easy to fix (though time consuming) except for the Nuke shaders.I'm sure if I looked a little harder I could fix those too
