<signal name="emission_shape_changed">
<description>
Emitted when this material's emission shape is changed in any way. This includes changes to [member emission_shape], [member emission_shape_scale], or [member emission_sphere_radius], and any other property that affects the emission shape's offset, size, scale, or orientation.
[b]Note:[/b] This signal is only emitted inside the editor for performance reasons.
