17.394. ábra - „Lava” options

Seed

  The lava generator uses randomization to generate the rendered lava. Seed determines the starting value. Using the same seed generates the same lava pattern.

Size

  This determines the size of the lava flows. Higher values create straighter lines.

Roughness

  This controls the straightness and amount of turns of the lava lines.

Gradient

  This allows you to set the gradient to be used for the lava effect.

Keep selection

  If a selection is present, the lava filter only creates lava inside the selection. This setting decides whether to keep the selection after the filter has finished.

Separate layer

  When enabled the lava is created on a new layer; when disabled the lava is added to the current layer.

Use current gradient

  When enabled this selects the current gradient as set in the Gradient tool.
