Effects from Ezekiel and Junior_Djjr. I changed the effects on the water, I hope the authors will not mind. Changed were: FxsFuncs.ini, particle.txd, effectsPC.txd, effects.fxp. The water became even more like water.
Added more underwater plants. The textures are not mine, I just changed them slightly. Screenshots may seem poor quality, probably because they were made under water and were subject to the effects of distortion of underwater reality)
