Sets or returns the right tangent Y of the fcurve key as a Double. The right tangent Y value is a positive offset from the current FCurveKey.Value.

The left tangent of the first key and the right tangent of the last key cannot be changed; if you try to set the tangent for one of these the property does nothing and returns S_FALSE in C++.

Tangent values only apply to standard function curves (where FCurve.Type = siStandardFCurve), the tangent value 0 is returned for all other function curve types defined by siFCurveType.

// get accessor Object rtn = FCurveKey.RightTanY; // set accessor FCurveKey.RightTanY = Object;
