public int getNbSimultaneousGPUMorph() {
        return nbSimultaneousGPUMorph;
    }
Return the number of morph targets that can be handled
on the GPU simultaneously for this geometry.
Note that it depends on the material set on this geometry.
This number is computed and set by the MorphControl,
so it might be available only after the first frame.
Else it's set to -1.

@return the number of simultaneous morph targets handled on the GPU
