The Aperture device expands or compacts every single feature on the terrain, similar to bokeh in a camera.

Properties

• Method: Choose whether to expand or compact the visuals on the terrain.
• Iterations: Number of aperture passes to perform on the terrain. Higher number of passes create pronounced effect at the expense of speed.
• Kernel: The Kernel is the shape of the aperture. Changing the kernel can change how the features on the terrain are modified.
  • Disk - Large, circular formation.
  • Diamond - Small, diagonal squares.
  • Cross - Small cross pattern. Can create predictable shape, use with masking for best results.
  • Octagon - Large, octagonal formation.
  • Rectangle - Large, diagonal squares.
  • Ring - Small, circular formation with steps/terraces.
  • Sobel - Rectangular stretches which retain corner shapes.
• Randomized: When on, each iteration uses a randomly selected kernel.

[!TIP]

To rotate the direction of the aperture kernels, use the @Rotator device before and after the Aperture device to change the direction, and then change it back. See Aperture.tmd example file for a demonstration of this technique.
