terrain fog boggles my mind.

im having a lot of trouble with this. i dont understand it at all. first, whats the difference between linear, exp1 and exp2? density doesnt change anything, and im not sure what the Z start and end values mean either.

could anyone point me in the right direction? thanks.

huh...... i wish i could explain that....

Can anyone answer that question?

haha i've seen that bunny video. "everyone else has had more sex than me... ooooo"

but on topic now, fog can be explained in a graph. the Y-axis is your distance from camera and the X-axis is fog density. Linear fog is simply a curve with a slope of x, meaning that for every x unit away from the camera, your fog is 1 unit denser. exponential fog is a curve, like x^2 or x^3. you get way denser fog with this option.

Z-start and Z-end is basically how far away from the camera the fog starts and ends. So again, if your fog starts at say, 1000, then up until 1000 units away from the camera, your fog density will be 0. Then at 1000 units away, your fog density will start to increase until your Z-end. Now say your Z-end was at 5000. This means that at 5000 units away from the camera, your fog will be at its maximum density, and you can't see past it. Depending on how close or far your Z starts and ends are, the rate at which fog will increase will be faster or slower. If the Z start and end is far apart, like say, 100 to 5000, then you'll have a very gradual increase in fog density. If they're closer together, like 100 to 200, then you'll have a very sudden increase in fog density, with almost no inbetween values.

wow i think that's the most in-depth exlanation for fog EVER. i'm proud.

It is indeed. Some rep for that.

hmm. thanks beam! ill give that a try.
