Leaks


Leaks

In: Mesh Adaptive/Mask Generators

Intermediate

Description

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

This node represents leaking streaks of dirt and grime coming from sharp edges. As streaks are generated with baked Position, they always run downwards.

Make sure to try changing the variation mask: because it drives the placement of streaks, it can have a much larger influence than with other Mask Generators.

Inputs

  • PositionGrayscale Input 
    Baked position map, used for streak directions. Required!
  • CurvatureGrayscale Input 
    Baked map used for streak placement. Required!
  • Ambient OcclusionGrayscale Input 
    Baked map used for internal effects and masking. Recommended, but you could use flat white instead.
  • Normal World SpaceColor Input 
    Baked World Space Normalmap, used for streak direction. Required!
  • Variation MaskGrayscale Input 
    Optional variation mask, enable by setting the override to True.
  • Mask (optional)Grayscale Input 
    Mask slot used for masking the node's effects.

Parameters

  • Level0.0 - 1.0
    Total level of the result. Progressively reveals the effect, affects length as well. Should be set fairly high to get long drips.
  • Contrast0.0 - 1.0
    Adjusts the contrast of the result.
  • Variation0.0 - 1.0
    Sets the amount of large-scale variation used to mask the streaks. Setting this value to 0 leads to full uniform streaks, so avoid this.
  • Lenght0.0 - 8.0
    Length of the streak drips. Setting this value too high at a small scale will lead to visible stepping. Play around with the Level too.
  • OccludeX, Y, Z, None
    Sets what direction the AO should affect.
  • Override variation maskFalse/True
    Enables overriding of the variation mask with a custom input slot. Using sparser or denser masks can be interesting and is a good way to control the drips.
