From Michael Platings, In Target, the default constructor is explicitly called on _target. This is necessary for FloatTarget and DoubleTarget so that _target is initialised to 0, otherwise you get a junk value. In MorphGeometry.cpp, UpdateMorph::link now links channels of the same index to the same target. Previously a new FloatTarget was created for each channel, so multiple animations didn't work.
