  95.       Solid Noise is a great texture maker. Note that this noise is
  96.       always gray, even if you applied it to a very colorful image (it
  97.       doesn't matter what the original image looks like -- this filter
  98.       completely overwrites any existing background in the layer it is
  99.       applied to). This is also a good tool to create displacement maps for
  100.       the <a class="link" href="plug-in-warp.html" title="10.11.¬† Warp">Warp</a> plug-in or for the

  142.             produces different results. Random seed can be entered manually or

  158.             If you check this, you'll get very interesting effects,
  159.             often something that looks much like oil on water, or

  169.             texture. Higher values give a higher level of detail, and
  170.             the noise seems to be made of spray or small particles,
  171.             which makes it feel hard. A low value makes it more soft

  180.             If you check Tileable, you'll get a noise which can be
  181.             used as tiles. For example, you can use it as a background
  182.             in an HTML page, and the tile edges will be joined
  183.             seamlessly.
