Sky

The Sky settings in Foxel allow you to control the overall lighting and atmospheric effects in your scene. You can choose from three different modes: Uniform Lighting, Image-Based Lighting, and Atmospheric Scattering. Each mode offers unique properties that can significantly impact the look and feel of your renders.

Sky Modes

Uniform Lighting

Uniform lighting provides a consistent light source across the entire scene, ideal for achieving a flat and even illumination.

• Color
  Set the color of the uniform light. This will affect the overall hue of your scene, allowing you to create different moods.

• Intensity
  Adjust the intensity of the uniform light. Higher intensity will result in brighter lighting, while lower intensity will create a softer effect.

Image-Based Lighting

Image-based lighting uses a cubemap to create realistic lighting effects based on an environment image.

• Cubemap
  Select an environment cubemap to use as the light source. This will provide dynamic lighting that reflects the colors and details of the selected image.

• Intensity
  Control the brightness of the image-based lighting. Adjusting this setting will influence how strongly the cubemap affects the scene.

• Blur
  Apply a blur effect to the rendered environment map in the background. This blurring does not affect the lighting itself but softens the appearance of the environment, creating a more diffused background.

• Angle
  Rotate the cubemap around the Y-axis to change the direction of the light. This allows you to adjust the lighting based on the desired perspective.

Atmospheric Scattering

Atmospheric scattering simulates the scattering of light in the atmosphere, creating realistic sky effects.

• Rayleigh Color
  Set the color of Rayleigh scattering, which affects the blue hues of the sky. This is particularly important for simulating clear skies.

• Rayleigh Density
  Adjust the density of Rayleigh scattering to control how much light is scattered in the atmosphere. Higher density will result in a more vibrant sky.

• Mie Color
  Define the color of Mie scattering, which affects the appearance of clouds and haze in the atmosphere.

• Mie Density
  Control the density of Mie scattering to influence the visibility of atmospheric effects. Higher density can create a more pronounced haze.

• Ozone Color
  Set the color of ozone scattering, which can add depth to the atmosphere and affect the overall color balance.

• Ozone Density
  Adjust the density of ozone scattering to simulate different atmospheric conditions.

• Phase
  Control the phase function, which affects the scattering behavior of light in the atmosphere. This can be used to simulate various atmospheric effects.

• Intensity
  Adjust the overall intensity of the atmospheric scattering effect. This will influence how pronounced the scattering appears in your scene.
