can any bodyu hekp me know wat is the significance of the circle shown around the infinite planes like water n ground in the top viewport. sample image shown below.
does this cirle have to do anything with the clipping or sumthing?
waiting for ur reply.
circle around the infinite planes.
ok thanx but wat is i am making a scene and sum of my objects falls outside this circle does that creat any problem in lighting and atmosphere of the scene?
actually in my scene there is sum problem am being unable to sort out which is that when i apply the presets provided to us for the atmospheres they behaves very abnormally. like clouds appeared to be burnt and the fog and haze are extremely glowing. does it have anything to do with the thing mentioned above that sum of my objects falls outside that circle?
thanx alot for the help.

Well, mostly I create my scenes so that they stay within the circle. I use real-world size relations so things like mountains, are really big and far away. The Aerial Perspective setting on the atmosphere editor Sky, Fog and Haze tab controls how Vue applies the fog and haze. Many atmosphere presets use 10 as the default. That means is is multiplying by 10 the atmosphere effects since most people tend to make smaller scenes. If you are reaching all the way over from edge to edge on the circle, set this to 1.
The other thing to mention is that if your model extends beyond the edge of the circle, VUE will NOT display anything outside of the circle. The model will exist outside of the circle, but VUE will not be able to display anything outside of it. To see or work on anything outside of the circle, move the camera to it and the circle will move.
If you are doing an animation, then the camera will move through your model, and so will the circle. As the center of the circle is the camera, any movement of the camera will move the extent that VUE can see.
One of my models was 15km in real units, and it fell outside of this circle. When I did my animation though, I could see all when I did a drive-thru.
thanx friends!
thankyou for quick replies.
your replies had been very usefull for for me. thanx alot. 
Regards
