RW - Scripted Deformer
To add this wave deformer, right-click on the "Realwave01" entry in the "Nodes" panel and choose Add Wave > Scripted.
With "Scripted" it is possible to create your own wave models based on Python scripting.
Active
With “No” the deformer can be disabled temporarily.
Weight
To reduce the influence of a deformer, decrease its weight. Valid settings are between 0.0 (inactive) and 1.0 (full influence).
Edit
A click on this button opens a scripting window with an empty function for updating the surface’s vertices. This part is filled with your script and RealFlow will execute the instructions to create the waves.
