- Alphas with soft edges (or alpha gradients) always have the downside that they are not visible through the water surface. Best example is the default alpha property flag of 237.
- Alphas wich need to be visible through the water always will have hard edges because alpha gradients are just not possible. Best example is 4854 alpha property flag.
... as this seems to be a limitation of the engine, even in Skyrim, does anyone know if OpenMW will allow us to have alpha gradients without such limitations?
