Sorry mvernon! I told you the colors backwards! (Feels sheepish and hopes for forgiveness.) MeInOhio is correct, in that you can correct MY error by selecting 'invert color.' As far as booleans are concerned, I, and others I have listened to here @ R'osity, have had lots of problems with booleans. Strange things sometimes happen at render time, while others happen when you do the boolean, then you end up spending HOURS fixing it in the vertex modeler. Not worth my time, UNLESS the effect your looking for can't be accomplished without it. I have to admit though that I haven't spent a lot of time in Amapi, and as such, maybe it treats booleans better then Carrara does. Hoping this helps better then my LAST sugestion. ;>
