Bottom To Top

Bottom To Top

In: Mesh Adaptive/Mask Generators



Generates a black and white mask based on baked maps and user settings. Similar to Smart Masks in Painter.

This generates a white to black transition from the bottom to the top of a model, useful for making geometry-based falloffs and selections.

  • PositionColor Input 
    Baked Position map. Required!
  • Roughness: Grayscale Input 
    This has nothing to do with PBR roughness, but is an (optional) variation map to break up the transition. Only appears when Roughness is set higher than 0.
  • Mask (optional)Grayscale Input 
    Mask slot used for masking the node's effects.


  • Level0.0 - 1.0
    Shifts the average level of the result between black or white, like a brightness adjustment.
  • Contrast0.0 - 1.0
    Adjusts the contrast of the transition.
  • Roughness_Variation0.0 - 1.0
    Determines amount of the Roughness map to blend in for variation. Increasing this over 0 reveals the map slot.
