Fog with Snow

I have successfully added snow, and made it a bit faster with more snow falling. Now, I'm trying to add a small fog across the battlefield. The problem is, it won't show up. Here is my .fx file.

Is there fog set up in your .sky file too?

No, I followed the tutorial by Taivyx, and he said to put it into your .fx file, which I did.

It all depends on the type of fog you're going for. Do you want atmospheric fog that prevents you from seeing off into the far distance? Or fog that's right up in your face, reducing visibility near you?

Probably reducing visibility near you, I kind of want a blizzard or snow storm effect.

You'll probably be best off with atmospheric fog that is really close to you, like Felucia or closer.

Ok, then I'll add the Felucia type fog. But I still don't know how to do it.

i think its this part in the .sky file

Code: Select all

Enable(1);
	FogColor(80,100,80,128);
	FogRange(-10.0, 62.0);
	EnableFadeAdjustWithZoom(0);

in combination with the viewranges

Really? Hmm, I'll have to try it in the .sky file. Like I said, I did it like the tutorial said and put it into the .fx file.
EDIT: Huzzah! It worked, other than the fact that I have to change the color. Thanks a lot. But I have one more question. How come the color has 4 numbers? I know the RGB, but what's the fourth one for?

RGBA for Alpha. The closer the value is to 0, the thicker the fog will be, I think.

Ah, okay. Thanks for clarifying.

Fiodis · Post by **Fiodis** » Sun Oct 24, 2010 5:33 pm

I thought 255 alpha = opaque and 0 = transparent.

Correct. Just like in the ZE water editor.
