Aquatic Surface

Advanced fully functional multi platform material-pack for water - over water surface, underwater, post-process volume, buoyancy, interactions and caustics.

Aquatic Surface is a well-optimized material pack and blueprint that implements fully functional configurable and realistic water effects.

Features:

• Water clip line effect
• Underwater and over the water surface and post-process volume
• Translucency support for underwater particles and meshes
• Three types of static reflection/refraction projections (box/spherical/planar)
• Animated caustics based on decals
• Buoyancy component
• UV mapping, vertex color flow, and texture color flow maps
• Over 100 parameters like translucency, fog depth, mapping, reflection, refraction, and wet color.
• Multiple material switches enable/disable some of the effects to increase quality/efficiency
• Very fast and GPU-friendly. 120-160 instructions depend on the used effects.
• Quality/Efficiency adjustment. cinematic (realistic reflections) and standard (static box projected cube-map)
• Water edge/coast (not using the distance fields)
• Sun and glittering effect on waves
• Fast underwater and surface scattering and god rays
• Implemented as the unlit translucent material
• Water holes for boats
• Fast physics-based interactions
• Character swimming implementation
• Interaction particle splashes
• Audio support
• World origin location

Limitations:

• the system is designed to work only with static lighting and prebaked reflections
