Overview

The Fluid Simulation Layer executes a fluid simulation on your terrain, which can be everything from really fast flowing water to more viscose substances like lava.


Parameters

  • Viscosity
    The viscosity of the fluid controls how fast and fluid the matter reacts. This allows you to change the appearance of your fluid from water to a thicker substance like lava.


  • Speed
    The speed at which the liquid travels over the terrain.


  • Wind Direction
    Controls the direction of the additional wind force.


  • Wind Strength
    Adds an additional wind force to the velocity of the simulated matter.


  • Wind Level Multiplier
    Links the wind strength to the current level step. This is helpful because the distance between pixels increases with each level step and the effect needs to be scaled with that in mind.


  • Wind Randomness
    Randomizes the wind direction, allowing for a more natural result.


  • Spawn Level
    In which level the sediment gets added to the terrain. 


  • Spawn Amount
    The amount of sediment added to the terrain.
