Hey Neyjour,

Thanks . Yeh the blurring was 'depth of field' in water. There are three elevels of blur to show things at three different distances, which maybe why it looks a little our of sorts... I liked the idea of doing it to suggest a more 3D effect... I need to play with this effect more.

The caverns that dont have linked tunnels are 'fill' more than anything, but access could be from the front but you doint see it because of the cross section. Or natural voids (like toads in flint nodules kinda thing)

The bottom tunnels are prevented from flooding my magical seals... its a fantasy maps and the tombs at the bottom were created by a powerful magocracy keeping their ancestors and items away from graverobbers
