No result. The only thing that makes any change is to set on “bUseOnePassLightingOnTranslucency”, the water is about 10% darker, but the borders looks worse, and the performance is the same.
Translucency sorting is set to -1, to solve this problem with the weapon beam: - YouTube
But changing to other values has no effect.
The fog is exponentialheighfog.
The water mesh bright depends of the size of the mesh. It’s a mesh that covers all the playable area, the 10x10 Km. Reducing the mesh scale, the fog bright decreases. Seems some problem with interpolation in the mesh faces.
