i tried with two scraps, one with the water the other with the blocks (or a block area). the blocks are above or below the water depending on the order of the scraps in the map. not sure this is what you wanted. marco ________________________________ From: Graham Mullan <graham.mullan@coly.org.uk> To: List for Therion users <therion@speleo.sk> Sent: Thursday, September 13, 2012 8:59 AM Subject: [Therion] clashing areas How do I get to show boulders or debris on the floor of a sump? Whether I put the debris area before or after the sump area, the rocks remain hidden by the water. In the end I hand drew some big boulders, after the water, which now are visible but also appear not to be wet.
