A material that provides a special texture to a [Sky], usually an HDR panorama. A resource referenced in a [Sky] that is used to draw a background. [PanoramaSkyMaterial] functions similar to skyboxes in other engines, except it uses an equirectangular sky map instead of a [Cubemap]. Using an HDR panorama is strongly recommended for accurate, high-quality reflections. Godot supports the Radiance HDR ([code].hdr[/code]) and OpenEXR ([code].exr[/code]) image formats for this purpose. You can use [url=https://danilw.github.io/GLSL-howto/cubemap_to_panorama_js/cubemap_to_panorama.html]this tool[/url] to convert a cubemap to an equirectangular sky map. A boolean value to determine if the background texture should be filtered or not. [Texture2D] to be applied to the [PanoramaSkyMaterial].
