Default environment properties for the entire scene (post-processing effects, lighting and background settings). The [WorldEnvironment] node is used to configure the default [Environment] for the scene. The parameters defined in the [WorldEnvironment] can be overridden by an [Environment] node set on the current [Camera3D]. Additionally, only one [WorldEnvironment] may be instantiated in a given scene at a time. The [WorldEnvironment] allows the user to specify default lighting parameters (e.g. ambient lighting), various post-processing effects (e.g. SSAO, DOF, Tonemapping), and how to draw the background (e.g. solid color, skybox). Usually, these are added in order to improve the realism/color balance of the scene. $DOCS_URL/tutorials/3d/environment_and_post_processing.html https://godotengine.org/asset-library/asset/123 https://godotengine.org/asset-library/asset/110 https://godotengine.org/asset-library/asset/678 The [CameraEffects] resource used by this [WorldEnvironment], defining the default properties. This [CameraEffects] resource will be used by all [Camera3D]s that do not define their own [CameraEffects]. The [Environment] resource used by this [WorldEnvironment], defining the default properties.
