However im haveing trouble with MR, im having constantly a line in the horizon thats like small gradient, and second i cant add fog ...
How you do it?
thank you guys
The "line at the horizon" sounds like you are seeing the "Aerial Perspective" of the skylight system. This is a built-in fog feature. Go to your "mr Sky" and change the "10% distance" for more/less fog, or turn it off.

If you want to use the oldschool max Fog, be aware that many max effects are low dynamic range, and gets confused by the high dynamic range of the sun&sky rendering. You can solve this by altering the physical scale to something very high, so that even sunlight fits into the oldschool "0 to 1" trange. Set physical scale to about 80,000 should do it.

See my blog for more details on physical scale stuff.
