Manipulate Generator properties in c#?

[blabz2007]

Doesn't seem to work - 

Code:

InputSplineShape splineShape = gen.GetModule<InputSplineShape>("Input Spline Shape");

        CSRectangle rect = splineShape.Shape as CSRectangle;

Cannot convert type 'FluffyUnderware.Curvy.CurvySpline' to 'FluffyUnderware.Curvy.Shapes.CSRectangle' via a reference conversion, boxing conversion, unboxing conversion, wrapping conversion, or null type conversion Assembly-CSharp, Assembly-CSharp.Player


Even if I try a cast - 

Cannot convert type 'FluffyUnderware.Curvy.CurvySpline' to 'FluffyUnderware.Curvy.Shapes.CSRectangle'

Thanks!
