Hi Hellborn- this is really great! I have begun playing with it and making a few modifications- mainly so that I can understand how your model works. I've successfully lowered the wave size and created a BIG VAST ocean out of it. These Procedural Terrains are really fantastic! It even freaks out Vue 5 when they first begin to render as it will report 8 hours, then 5 hours, and then rapidly reduce down to only a few minutes. I guess some mechanism in Vue's renderer quickly figures out what needs to be rendered from the camera viewpoint and then concentrates the rendering just in that field of view... Your model makes an ideal infinite ocean waves terrain and is tremendously better than Vue 4's old method of tiling meshes or terrains to create oceans. I think we are just scratching the surface of how good this is going to be! I'll post some pictures once I can get the rendering done. I'm doing them at 1024 x 768 with Global Illumination, so it will take a little while...
