Kloot - Some feedback on alpha masking coastlines and the pixelly edge problem. See these two pieces of screenshot taken while flying. The first is the problem we've been having. In the second I did a very quick paint with a sea colour along the edge of the coast. Its a wavy inexact line but looks a bit better. Unfortunately a single block of sea colour still creates an obvious transition when up against the background multi-shaded sea.
Thanks Phil, I will give the image a quick paint along the edge
