Underwater

The Underwater feature in Oceanology enhances the underwater environment for both OceanologyInfiniteOcean and OceanologyLake, offering immersive post-process settings, volumetric fog, and visual effects.

Overview of Underwater Setup

Enabling Underwater Mode

  1. In the details panel of either BP_OceanologyInfiniteOcean or BP_OceanologyLake, locate the Underwater category.

  2. Enable Underwater Mode and adjust the settings as needed.

Underwater Box Volume Component

  • The underwater experience is defined by the Underwater Box Volume Component, determining the boundaries of underwater rendering.
  • Ensure this component is present to correctly apply underwater effects.

Key Parameters

  • Fog Density: Controls underwater fog density, adjusting visibility.

  • Sun Power: Defines sunlight penetration, affecting underwater brightness.

  • Depth Color Absorption: Adjusts light absorption at different depths.

  • Vignette: Use Vignette Dark and Vignette Edge settings for an immersive vignette effect.

Color Customizations

  • ExponentialFogColorHigh/Low: Control fog gradient appearance.

  • SceneColorDeep/SceneColorShallow: Define deep and shallow water colors for natural transitions.

Post-Process Material

  • Use the default underwater post-process material (M_UnderOcean_PostProcess_Volume_Inst) or create a custom one to suit your needs.
  • This material applies effects like distortion, light scattering, and color adjustments to create an authentic underwater atmosphere.

Distortion Effects

  • Distortion Amount, Intensity, Scale, Speed: Control underwater visual distortion for a dynamic effect.

  • Distortion Texture: Assign a custom texture for underwater distortion if needed.

Volumetric Lighting Configuration

  • You can also switch to volumetric lighting for a more immersive underwater experience. This setting enhances light scattering, creating realistic underwater illumination.

Mask Integration for Underwater Objects

  • In the Mask page, you can properly mask objects underwater, ensuring they blend naturally with the underwater environment.

  • Ensure the underwater settings are tested under different lighting conditions to achieve the best immersive experience.
