I'm trying to find whether there's a way for some objects to be excluded from the fog, that is: to appear as if there had no fog on top of them whatever the distance from the camera. That would be very usefull to efficiently draw far away objects like sky and backdrops.. Because as of now we have no way of having a far-away backdrop and a fog at the same time because the sky is affected and it doesn't look good.
(You can see that often in other games like in WoW for instance. See this screenshot. Notice how the mountains are greyed out by the fog but the sky behind is perfectly clear?)
I'm worried because I haven't seen that anywhere in Uru, but I hoped someone might have an idea?.. Maybe a shader effect or a special flag?
