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

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

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

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

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.

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

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