Fog Settings bug?

[Jamey]

Alternatively, the Nexus PRP files could be patched to hardcode the fog colour/type.

plFogEnvironment is a powerful way to have different type of fog on different objects... I'm not sure why Cyan never created a way for themselves to use it :\

I never knew the PRP files could be patched to hardcode fog settings

I'm thinking that would be the way to go in terms of fixing this whole fog issue, rather than rewriting the F'ni & Sum files. A Patch could be made that would hardcode the nexus PRP files, and it could be released with Drizzle/Offline KI perhaps?


As for plFogEnvironment, I am curious, what are some other neat things we could see in ages by using these methods? Does this mean it will be possible to have 2 different color fogs in the same age? How does that work?

I've never heard of this setting before and would like to learn more.

You've never heard of it because it is never used. Cyan doesn't use it anywhere, and the only way to add a plFogEnvironment is with libHSPlasma hacking and PRC.

Cyan never uses manual plFogEnvironments is specifically what I meant. What they do is parse the FNI file, generate a FogEnvironment, and set that as the FogEnvironment for any object that doesn't have its own manually referenced.

You could use this to have an Age with two different types of fog, but remember that the fog is per-object. So if your wall has green fog and your bookcase has pink fog, there will be no blending or nice transition.

The way you describe it is different from the python induced Age-wide changes that have been tried so far; which makes it much more flexibe. (although a little more difficult to setup)
This could be used for some fun special effects or to treat differently a specific fog area of an Age (like in Ahra Pahts). You could also use it to darken an area with a dark fog (for instance a tunnel or something similar in conjunction with a light soft-volume).
You could also use it for an underwater area.

I've been looking for a while at ways to fake a volumetric/layered fog in Plasma, to keep it on the ground.. And it always comes down to using layers of transparent planes, particles and other alpha tricks, which can be quite performance demanding. especially on large scenes. And it doesn't always looks good. (see sand storms in Minkata or Laki)
This could help to a certain extent..

Oddball question: is it possible to 'invert' a fog? Have it so that it becomes thinner with the distance?

I could easily ship a Nexus.fni file with the next Offline KI to always set it to the Relto fog settings (since coming from Relto, everything looks just right).
The sum file won't even need updating, since it's a dummy anyway if you have the Offline KI installed.

Obviously I haven't. I thought the Offline KI only created dummy sum files for fan ages.

And yes, those lines which Cyan commented out are the Relto fog settings. In fact only a very thick fog would carry over to the Nexus. It is too small to see any fog with the settings Cyan normally uses.

That would be awesome! If it fixes this whole fog problem, then I'm all for it

But Jamey has
It's the other way around: The Offline KI has these sum files for all POTS ages (they are just zipped in the archive, nothing is created) - I can hardly know which fan-ages get installed. Drizzle creates these kind of sum files for the converted ages. For fan-ages, it's up to the author.
