The flowmap tools in Houdini work per-point, while the final result in a game engine will be run per pixel. This HDA allows you to preview the final per-pixel effect at high quality.
The only requirement is that the flowmap data has been converted to @Cd, which can be done with the 'Flowmap to Color' sop. This HDA provides extra controls for speed, distortion, and while it ships with a preview water texture, allows you to use your own water surface preview texture.
Texture to preview flowmap, default is to use a texture embedded in the HDA.
Number of times the texture repeats in the uv’s of the input geometry.
Speed of the flowmap animation.
Amount of warping applied to the flowmap preview. Larger values create a more pronounced effect, but can introduce ghosting artifacts.
Set if this node reads motion vectors from @Cd of the input geometry, or from a file texture.
Path to the flowmap texture.
