Additive Shader bug when 'recieve fog' is enabled

It looks like it's not blending additive materials with fog properly

There are similar issues with refractive shaders also

Making fog work on just additive/refractive is one thing, but a generalised system sounds tricky! This begs the question - how should fog affect all combinations of blending? For additive in particular it should render the fog with a black color, which makes the fog color simply make the additive blending, well, stop adding (Since x + 0 = x)

I agree a generalised system is hard to do, especially when you have custom blend modes available.

Perhaps when it comes to custom blend modes, specifying a custom fog colour could be an option? so for example, for a modulated x2 blend mode I could specify a fog colour of 127,127,127, or for multiplicative, 255,255,255 etc?

Fog overrides should be provided in any case
