Just in case, I'll remind you. If you just want to use a ready-made fog example. The parameters: Height_Volume_Bias, Height_Mask_Bias are calculated from the world space by default and depending on the location by height on the map, they can change the configured option. Therefore, they may have to be adjusted. These parameters can be converted to local space, but you will have to adjust the parameters: Height_Volume_Bias, Height_Volume_Hardness, Height_Mask_Bias, Height_Mask_Hardness.
Volumetric fog by default is not very light. The drawing distance of Volumetric Fog in the settings affects - ExponentialHightFog. There is a dependence on the settings in the material (many things can be disabled depending on the needs). But the settings that you enter in the command line have the greatest influence: Quality of fog at a distance: r.VolumetricFog.GridPixelSize 4 (the less the better the quality, 8 - default) Fog Jitter (Fog shadow jitter): r.VolumetricFog.GridSizeZ 256 (the more the better the quality, 128-default) 26:12 - Impact on Performance

am gonna buy it but wanna know how it affect the performance?
