If the material is translucent, then the fog affects to it in that way.
I have touched options, and the only that works is to disable “allow fog”, but then the remedy is worse than the disease… And the material can’t be opaque, it’s the sea, lakes, etc. water.
The fog start distance is set to 0. Setting it to 30000 the result is better, but then the fog doesn’t affect to the near objetcs or the terrain.
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.
