I tryed to implement the ripple effect from Vereshagin Roman Vladimirovich's Q3 BSP Loader, eventualy i got it working, but there is a odd sideeffect from the blending. Fig 1 shows how it should look(strangly it works fine when looking at it from one direction) and Fig 2 shows the screwup. If im correct 2 parts of the "water" are being added together to make a less transparent area. My question is does anyone know a way to stop this. (without resorting to no transparency).
