I created this personal project to evolve my skills in FX and experiment with the Ocean Spectrum nodes. I added and scattered these assets from Chao's Cosmos, and used the movement of the grid to manipulate the normals, in order to get the movement and orientation on the scattered assets.

Software: Houdini FX - Vray - NukeX
I used an attribute interpolate node to keep my scattered points bound to their position. For optimisation purposes, I used the frustum camera HDA, to delete any points not visible to my camera, in order to only scatter points where they would actually be visible. This allowed me to add more grass into the scene, whilst keeping my viewport fast and efficient.
