A problem with the Kinect self-keyed graph in Unity

when developing with kinect2.0 's development package in unity, a color map of the person who removed the background is displayed, the user map type is non-rawusertexture, the display user map is checked, but only the white image area is always displayed. Previous use has not arisen this problem, for me this rookie, very confused. However, I did not give up, after the comparison, tracking found the problem, the original is shader not set up correctly led to the inability to complete the cutout.
After trying, that's the problem.
Now solve the problem:
Copy the relevant shader to the resources folder.
