Should anyone else ever need to try this, there turns out to be a very easy way to do it, assuming that your solvent mask is in ccp4 mask format.
1. use mapmask mskin $MASKFILE mapout $CONVERTED_FILE 2. load $CONVERTED_FILE into pymol, treating it as a normal map. Contouring at 1.0 will display the solvent mask correctly. Of course, it would be better if this had occured to me before spending a few hours in the depths of layer2/ObjectMask.c ; but that's Mondays for you.
