Ok great thanks guys, will do some testing and see what floats to the surface. Will report back when I work out the best method.
Many thanks again.

It would probably take a lot of time to tweak the bumps into convincing waves... and render it. As far as I know there are no renderfarms for RS. Honestly, I would consider using other software for the ocean and post process it with the RS rendered stuff, unless you need realistic reflections and refractions of your RS scene in the water. For example Blender has a great Ocean modifier, plenty of tuts and examples on youtube. And beware of render artifacts when using displacement, sometimes black edges appear! Good luck and please post some WIPs! -Mark H _______________________________________________ User-list mailing list [email protected] http://realsoft.com/mailman/listinfo/user-list_realsoft.com _______________________________________________ User-list mailing list [email protected] http://realsoft.com/mailman/listinfo/user-list_realsoft.com
