I have two questions about fog. Please help me out, if you can. Smiley

1) Is it possible to add 'more than 1 fog'? Like you can add light0, light1, etc, with light. Is the same possible for fog? So that you can create some kind of fog bank. If it isn't, how would I create such things otherwise?
2) You only can set the fog start and end, right? how would I put fog on the sides, so that you have a rectangle around which the fog is. If that isn't possible, how would you make the fog look all around, so that you see fog wherever you place the camera. (I would give you an example, but the only example I can think of is RuneScape HD.)

Thanks,

~Matt

OpenGL Fog is an operation that reads the depthbuffer and calculates a blending operation for it, using the fog color.

You cannot have volumetric fog out of the box, unless you code it yourself.
