Patchwork 3D 2024 X7

Sun and Sky

Warning

The Patchwork 3D real-time sun cannot be used at the same time as the Iray sun and sky. If both lights are enabled simultaneously, only the sun and sky in Iray will be used.

Iray offers a simulation of the light of the sun and the sky.

When the Sun and sky option is enabled, a sun type illumination is added, an infinite plane is used as the ground, and an environment representing the sky is displayed.

The Multiplication value adjusts the environment's luminosity.

The sun settings include:

  • The solar disk intensity

  • The solar disk scale

  • The solar glow intensity

  • The sun's position, which can be set in the Position of the Real-time Sun editor

Sun parameters for Iray.

The sky settings include:

  • The night color

  • The haze level

  • The red- or blueshift. Positive values will produce a redshift, while negative values produce a blueshift.

Sky parameters for Iray.

The ground settings include:

  • The ground color

  • The horizon height

  • The horizon blur

Floor parameters for Iray.

Soft shadow settings include:

  • the use of OpenGL parameters, cf. Use OpenGL parameters

    This setting ensures that the OpenGL visualization of your model in the viewport is similar to the Iray rendering. You can then change the Shadow smoothness parameter from the Real-Time sun editor to get soft shadows in Iray.

    OR

  • the use of custom parameters, cf. Use custom parameters

    • The Distance from the sun to the scene.

    • The Sun radius.

    • The Intensity factor .
