## **Parameters**

<table><thead><tr><th width="199.7999267578125">Property</th><th>Description</th></tr></thead><tbody><tr><td><strong>Strength</strong></td><td>Controls the strength of the filter effect on the terrain.</td></tr><tr><td><strong>Sign</strong></td><td>Inverts a part of the computation, leading to a different result.</td></tr><tr><td><strong>Step Size</strong></td><td>The step size of the filter particles. Increase this to get more elongated features.</td></tr><tr><td><strong>Sample Size</strong></td><td>The sample size the algorithm uses to compute the terrain normal for particle flow computation.</td></tr><tr><td><strong>Depth</strong></td><td>Changes the overall depth feeling of the filter effect.</td></tr></tbody></table>
