tfErosionHydraulic simulates the realistic erosion of terrains by precipitation, using one of two modes.

Properties

Mode

Hydraulic (2D Particles) is a 2-dimensional simulation and is therefore a much quicker filter, using heightmap information.

Hydraulic (X-Particles) is a 3D particle simulation filter, allowing much more control, but taking longer to simulate.

Particle Count

You can decide how many particles you would like used in the scene.

By default, this Particle Count is set at 10000.
