	<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:
 		
		- DOF Blur
		- Motion Blur
		- Bloom
		- Tonemap (auto exposure)
		- Adjustments
