	<description>
		Resource for environment nodes (like [WorldEnvironment]) that define multiple environment operations (such as background [Sky] or [Color], ambient light, fog, depth-of-field...). These parameters affect the final render of the scene. The order of these operations is:
		- Depth of Field Blur
		- Glow
		- Tonemap (Auto Exposure)
		- Adjustments

			If [code]true[/code], the screen-space ambient occlusion effect is enabled. This darkens objects' corners and cavities to simulate ambient light not reaching the entire object as in real life. This works well for small, dynamic objects, but baked lighting or ambient occlusion textures will do a better job at displaying ambient occlusion on large static objects.

		</member>
		<member name="ssao_power" type="float" setter="set_ssao_power" getter="get_ssao_power" default="1.5">

			Sharpness refers to the amount that the screen-space ambient occlusion effect is allowed to blur over the edges of objects. Setting too high will result in aliasing around the edges of objects. Setting too low will make object edges appear blurry.
