Graphics programming - Unity 3D shaders - 005.

If you working with shaders and you get this error

Shader error in '': Parse error: syntax error, unexpected TVAL_ID

Go to console area and find where is the line of source code ...

Shader error in '': Parse error: syntax error, unexpected TVAL_ID at line 15

In my case was an old defined source code ZWriteoff, after I change it with ZWrite Off the shader is compileted.
