Absolutely, that's it! I found a quick work-around in my terrain engine, though, but comparing any terrain vertices to the water plane height, and adjusting up or down any vertices that are at the same height, to avoid surface fighting for top dog in the Z buffer.
But offset bias is definately the "proper" way to go. Thanks, Scott ----- Original Message ----- From: "Simeon H.K.
