Fog

[Frits]

What do I have to change in this piece of text to get a little fog back?
I don't understand where all the values stand for.

#--Fog settings--
#Graphics.Renderer.SetYon float yon
#Visibility distance
Graphics.Renderer.SetYon 100000

#Graphics.Renderer.Fog.SetDefLinear float start, float end, float density
#Fog depth
Graphics.Renderer.Fog.SetDefLinear 1 1000 1

#Graphics.Renderer.Fog.SetDefExp2 float end, float density
#Graphics.Renderer.Fog.SetDefExp2 100000 20

#Graphics.Renderer.Fog.SetDefColor float r, float g, float b
Graphics.Renderer.Fog.SetDefColor 0 0 0

#Graphics.Renderer.SetClearColor float r, float g, float b
Graphics.Renderer.SetClearColor 0 0 0

All those lines beginning with a # mark are comments and gives a few hints about what the following line does. "Float" tells you that the following named parameter is a number with a fractional part, i.e. it can have decimals, not just "whole numbers".

So, with the linear fog params, you have the three values:

start - At this distance from you, there is no visible fog
end - Everything that is this far from you and farther, is lost in the fog (if density is 1). This would be the value you want to decrease.
density - Maximum effect by the fog thickness, i.e. what you have at the end distance and beyond.


Somebody else wil have to explain the square parameters. :7

SetYon - Visibility distance.
SetDefLinear - Fog density if I recall
SetDefColor - Color of the fog
SetClearColor - Sets the color when there's nothing to display on the screen (which should never happen, but will if a bug occurs)

At least I'm pretty sure of it.

Thanks guys, now it gets a little clearer to me but this leaves me with a question though;
The values for: float start, float end, float density are 1, 1000, 1 so there should be any fog.
Do I have to change the values for float r, float g, float b to make it visible?

No, like Kato said, that would be if there was a bug in the rendering, if I remember correctly. You can leave those set to 0.

Hmm, if it is your skydome that stubbornly resists the mist shroud, that is exactly you'd expect if you have the "NoMist" button (material property) selected.

Thanks guys, sorry for not being clear but with the float r, float g, float b I mean the values for SetDefColor Andy .
I'm going to try the 'NoMist' button Jojon.
