SkyboxPlus is a collection of skybox shaders for Unity.

Cubemap is a basic cubemapped skybox shader. The main difference from the standard skybox shader is that it can be rotated not only around the Y-axis but also around the X/Z-axis. It also has a saturation slider, which is used for adjusting the colorfulness of the cubemap.

The MIP level option controls the blurriness of the cubemap. It can be used for reproducing a bokeh-like blur effect on the background.

To make this option effective, it’s required to turn on the “Glossy Reflection” (pre-convolution for glossy reflection) switch in the texture importer settings. Also, it’s recommended to use the [Skybox component] skybox to apply different MIP levels to the camera (background) and lighting (reflection).

Hemisphere is a basic gradient skybox shader. It only has three color values (color at north pole, on equator and at south pole). The shader linearly interpolates between them.

Gradients is an additive gradient skybox shader. Each gradient has a direction vector and a color value. The shader interpolates along the vector, from black to the given color. The shape of the gradient can be adjusted with the exponent property. Up to four gradients can be given at the same time.
