	<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
