A resource referenced in a [Sky] that is used to draw a background. The Panorama sky material functions similar to skyboxes in other engines, except it uses an equirectangular sky map instead of a cube map.
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 cube map to an equirectangular sky map.

<brief_description>
[Sky] [Material] used for a physically based sky.
</brief_description>
<description>
The [PhysicalSkyMaterial] uses the Preetham analytic daylight model to draw a sky based on physical properties. This results in a substantially more realistic sky than the [ProceduralSkyMaterial], but it is slightly slower and less flexible.
The [PhysicalSkyMaterial] only supports one sun. The color, energy, and direction of the sun are taken from the first [DirectionalLight] in the scene tree.
As it is based on a daylight model, the sky fades to black as the sunset ends. If you want a full day/night cycle, you will have to add a night sky by converting this to a [ShaderMaterial] and adding a night sky directly into the resulting shader.

<brief_description>
Type of [Sky] that is generated procedurally based on user input parameters.
</brief_description>
<description>
ProceduralSky provides a way to create an effective background quickly by defining procedural parameters for the sun, the sky and the ground. The sky and ground are very similar, they are defined by a color at the horizon, another color, and finally an easing curve to interpolate between these two colors. Similarly, the sun is described by a position in the sky, a color, and an easing curve. However, the sun also defines a minimum and maximum angle, these two values define at what distance the easing curve begins and ends from the sun, and thus end up defining the size of the sun in the sky.
The ProceduralSky is updated on the CPU after the parameters change. It is stored in a texture and then displayed as a background in the scene. This makes it relatively unsuitable for real-time updates during gameplay. However, with a small enough texture size, it can still be updated relatively frequently, as it is updated on a background thread when multi-threading is available.

The [ProceduralSkyMaterial] uses a lightweight shader to draw the sky and is thus suited for real time updates. When you do not need a quick sky that is not realistic, this is a good option.
The [ProceduralSkyMaterial] supports up to 4 suns. Each sun takes its color, energy, and direction from the corresponding [DirectionalLight] in the scene.
