DepthBiasedAlpha doesn't work well (with different viewing angles) to tell the truth. It is better to use vertex paint, because not only it is more accurate but it saves alot of instruction count which is something desirable in games. Painting manually isn't intuitive but it is a fair trade-off.
Sweet, beacuse i realize you blend it using Depthbiased alpha, but the opacity is the issue, i want the ocean to fade out and become less transparent along the shore but the foamy stuff to be fully visable. For the time beeing im just using vertex colors. But it would be nice to have something moore procudural.
