[quote="RambOrc":5m0dntgb]What I did was first I made a 3D water sector close to the shore, then defined horizon for the far side linedef. It looked perfect except for the one little thing that the "fake" part of the water was dark,
I believe it is simply because engine rendered base water texture for horizon, without applying transparency. Well, it can't because it does not render whole sectors stack there (region above transparent water, water surface and below region).
I also think, maybe if an appropriate sky texture/skybox is made with water/sky horizon drawn, that may solve the problem somehow.
