		Omnidirectional light, such as a light bulb or a candle.

	<description>
		An Omnidirectional light is a type of [Light] that emits light in all directions. The light is attenuated by distance and this attenuation can be configured by changing its energy, radius, and attenuation parameters.
		[b]Note:[/b] Due to current rendering engine limitations, only 8 OmniLights may affect a single mesh [i]resource[/i] at once. Consider splitting your level into several meshes to decrease the likelihood that more than 8 lights will affect the same mesh resource. Splitting the level mesh will also improve frustum culling effectiveness, leading to greater performance.

		<member name="omni_attenuation" type="float" setter="set_param" getter="get_param" default="1.0">
			The light's attenuation (drop-off) curve. A number of presets are available in the [b]Inspector[/b] by right-clicking the curve.
		</member>
		<member name="omni_range" type="float" setter="set_param" getter="get_param" default="5.0">
			The light's radius. Note that the effectively lit area may appear to be smaller depending on the [member omni_attenuation] in use. No matter the [member omni_attenuation] in use, the light will never reach anything outside this radius.

			Shadows are rendered to a dual-paraboloid texture. Faster than [constant SHADOW_CUBE], but lower-quality.
