Erosion brushes for sculpting

Now when we already have cloth brushes, I think erosion would be the next logical addition to the set of simulation brushes and it would improve the life of terrain creators a lot.

Types of erosion to be selected would be at least these

• Water / flow erosion (brush would somehow simulate rainfall to the selected area. It would cumulate materials to bottom and those parameters should be able to be edited)

• River erosion (the brush would simulate a river to be started from the location of brush stroke)

• Coastal erosion (this would create a water erosion to the selected area. The difference to the wind erosion I think should be that this has an emphasis the shores and bottom of the cavities)

• Wind erosion (brush would erode the material from the direction of brush stroke, expect Z-axis, so that it would create towers or caves etc.

• Chemical / rust erosion (this would make surfaces erode slowly and make it bubbly and cracking etc.)

• Melting erosion. (This could be used for icebergs, melting plastic or iron or volcano etc.)

To control what materials are being eroded, you should have an ability to set textures to the brush or the material / hardness so that the brush knows which materials are harder and therefore erodes more slowly. Also you need an ability to control material cumulation. Does the material move somewhere or will it disappear and how fast? Also simulation limit and falloff are needed in a similar way as the cloth brush does it.

We also need a way to map the areas with the same brushes as vertex color paint layers, because you need that data for texturing. So you should be able to create a color data layer for the different types of erosion.
