Is it possible to change the far clip distance more than max value? The problem is, that my object disappears, when its far away. That happens because the clipping doesn't allow greater values that 100m unless I change the unit presets and therefore scale the whole object. That would be not so good, because I would have to rescale it than after exporting to get it right in unity. If I could just adjust the clipping distance a bit more that would be cool. Is there maybe a way to move the clipping spectrum from 10um-100m to something like 10cm-1km without changeing the whole scaling.

PS: I wanted to add the tag 'clipping'; can someone create that?
In 3D view, Object mode. Press N then change the Start and End of clip to whatever you want.
