Draws a waterline lens effect for partially submerged camera's, through an innovative technique. Unlike in many games, it won't be required to snap the camera to sit either above or below the water, or resort to other tricks.

Compatible with the Dynamic Effects extension. Effects such as ripples and shoreline waves also affect the camera's water line.

What's new?

• Completely rewritten for Unity 6’s Render Graph

• Redesigned to work exclusively with defined underwater areas (box collider triggers)

• Particle Effect controller, makes effects follow the camera underwater up to a specific depth (eg. sunshafts)

• Easier integration for transparent materials. The render queue of the effect can now be set

• Revised shader for transparency, used for particle effects underwater.

• Optimized technical design, no longer uses full-screen post-processing

• Support for mobile hardware.

• Blur/distortion effects have been removed (not implemented in any AAA games either, will be reconsidered based on feedback)

🌊 Features:

• Underwater fog based on the water's deep/shallow colors.

• Waterline rendering for partially submerged cameras (supports split screen)

• Scene lighting is translated into the underwater fog, including sub-surface scattering. Reacts to dynamic directional and ambient lighting.

• Caustics rendering on geometry. Directional projection option.

• Underside of the water is correctly shaded, to seamlessly match.

• Includes sub-graphs to add underwater fog support for transparent Shader Graphs (+ASE)

🚧 Limitations:

• Does not support multiple cameras simultaneously (eg. split-screen).

• Designed for oceans, lakes and ponds. Dioramas or aquariums aren't possible.

• Can't mask underwater (eg. submarine windows)

• Not a volumetric fog/light solution, but rather depth-based.

• Requires a single water level (incompatible with rivers/planets)
