In Maya API 2.0 setResult() always returns a list to caller.
In python command I have self.setResult(0.5)
Then I call from mel script I receive [0.5]
$res=`getCustomPaintValue -1 4522`;
print("------- getCustomPaintValue1: " + $res + "\n");
I console I have error:
// Error: print("------- getCustomPaintValue1: " + $res + "\n");
// Error: Line 2.47: Illegal operation "+" on data of type float[].
I can use $res[0] in this command, but it doesn't work for other calls.
How can I return command result as float not a list?
Thanks.
