Custom UI Material Issue
Related to this question, I have a material I am using in the UI and modifying one of the shader property values with code, so that I can create a progress bar. 
However if I add _ColorMask("Color Mask", Float) = 15 to my shader, then this progress bar behavior vanishes. No matter what alpha cutoff value I set, it always looks like this: 
Leaving the ColorMask out, I get the behavior I want, but Unity complains that the shader lacks the ColorMask property.
Material Progress doesn't have _ColorMask property
