public void setNbSimultaneousGPUMorph(int nbSimultaneousGPUMorph) {
        this.nbSimultaneousGPUMorph = nbSimultaneousGPUMorph;
    }
Sets 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.
WARNING: setting this manually might crash the shader compilation if set too high.
Do it at your own risk.

@param nbSimultaneousGPUMorph the number of simultaneous morph targets to be handled on the GPU.
