3D Volume Mask


3D Volume Mask

Description

Creates a black-and white mask volumetric mask, based on the input Position map. Effectively allows you to translate a 3D selection to 2D. See 3D Linear Gradient for a similar effect.

Can be tested with Cube 3D GBuffers if you don't have a baked Position map and mesh. See example below.

Parameters

  • Shape: Cube, Cylinder, Sphere
    Change the shape of the volume mask.
  • Scale: 0.0 - 1.0
    Set the global scale for the effect.
  • Size: 0.0 - 2.0
    Set the non-uniform scale on X, Y and Z axes separately.
  • Position Input: UV Position, World Space Position
    Choose whether the volume is moved in 2D or 3D space.
  • Position UV:
    Allows you to move the volume in X and Y directions, when set to UV Position mode. This makes most sense when you manipulate the 2D/UV view.
  • Position: (Color value)
    Allows you to move the volume in X, Y and Z directions, when set to World Space Position mode. This makes most sense if you want the volume in an exact 3D location.
  • Rotation: -1.0 - 1.0
    Rotate the volume.
  • Feather Width: 0.0 - 1.0
    Set the Fall-off distance/fading of the Volume shape.
