Massing Model:

  • Creation of the Base Shapes
  • Low Resolution

Massing Model Detail


Seeding:

  • Heightfield Noise, HeightfieldDistortByNoise, HeightfieldDistortByLayer(New)
  • Important because without it the Erosion would be boring and just fall down from the Top to the Bottom
  • Still low Resolution

Lobing:

  • Cutting into the Mountain (Important to do that before the Main Erosion)
  • Low Resolution Erosion that tries to cut into the Main Features
  • Nice big Breaks & Chunks

Remap:

  • Artificially increase the Elevation of the Erosion to something thats higher than what would be normal in Reallife
  • Goal: Create different looking Layers in the Mountain
  • Afterwards create a new Layer with a Massing Model on Top of that (Do 2-3 times)
  • Still low Resolution

Sample Up & Shape:

  • Resample and then Sahpe → Repeat a few Times
  • Shaping:
    • Distort it even further so the Erosion will not be boring
    • Add Swirls, Noise etc
      • HeightfieldDistortByLayer

Re-Seed:

  • Add more Obstacles for Erosion to hit

Erosion:

  • 3 Erosion Passes:
    • 1 Lobing
    • 2

Shaders/Scattering
