    Asset Pack
    This product contains an assortment of Unreal Engine assets which can be imported into a pre-existing project of your choice.

I am currently working on the Fluid Flux system, so Aquatic Surface will not be developed or extended anymore due to time limitations. Thank you for your understanding.

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

[Interactions & Buoyancy]

[Getting Started Tutorial]

[Vertex Flow Tutorial]


  • 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


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