Question about Fog
by Paul Yoskowitz · in Torque 3D Professional · 01/31/2011 (7:18 am) · 9 replies
if you create fog for a level, and just have a sun object in, it seems to look fine. however, if u have any other 'sky object', it doesnt seem to be effected by the fog - the effect stops with the ground.
i have mnts in the distance that are effected by the fog, but then it goes to a crystal clear sky right above it.
is that how it was supposed to work?

Paul, if you could provide a screen shot or a more wordy explanation, I am sure this is something the community could help with.

for the sky, use a Sun object only. what youll get is a fog that goes up as high as the eye can see.
replace the Sun object with a ScatterSky object. youll notice that the landscape (in my mission its mnts) are fogged out, but the sky is crystal clear. it seems like *too* sharp of a difference. ive played with the settings and cannot blend the two.
Im not saying its a bug or an issue, im more curious to know if its uspposed to work that way.

in the LevelInfo object, set fogDensity 0.05 - fogDensityoffset 0 and fogAtmosphereHeight 0for the sky, use a Sun object only. what youll get is a fog that goes up as high as the eye can see.

This may well be solved by a combination of variable settings.

Im not sure if it is a bug or not, ether. I will set up a test mission with the criteria you mention and see what results I can achieve. This may well be solved by a combination of variable settings.

I have not yet used this Resource ( ScatterSky Z-Offset Hack ), but it may be the perfect solution for you or at best a great place to start.

Using your above settings in a test mission, I observe your original point of concern. The best looking effect I could achieve was by also adding an CloudLayer.

I have not used the Resource that you pointed out. This was more of a curiousity to me and i was hopin that the GG Team might have a say on this one way or the other. I would happily write this up as a bug if one of them says that this isnt the way that its supposed to work. If this is as its intended, then all is well.

i can do a bit of adjusting with the cloud layer, very true, and a good point.I have not used the Resource that you pointed out.

On the other hand, once one understand the power of ScatterSky, and with some creative thinking, a good level-designer will be able to do much more then simply use it as a sun light. It is unfortunate it takes over the 'sky box'.

I believe this is indeed the way this feature is designed to work. The inconsistence of naming and operation conventions in this regard is not your query alone, an example to mis-logic of T3D design I have pondered many hours (I reason, such as this are left overs from evolving engine design).On the other hand, once one understand the power of ScatterSky, and with some creative thinking, a good level-designer will be able to do much more then simply use it as a sun light.
