Max Displacement Frame
When generating volumes and points, this node needs to calculate the maximum horizontal and vertical displacement in the input ocean waves. If this parameter is enabled, the displacement will be estimated only once at the specified frame, which is fast, gives a stable point output, and it typically accurate enough for good results. However, in the case of animated wave amplitudes or quickly varying instacing geometry, it may be necessary to continuously re-calculate the displacement by disabling this parameter.
