Well, the paving stones are a single plane with displacement. It has worked fairly well, but was it worth it? Took me all afternoon to do. Sculpting is the other main option. I’m considering using displacement in situations where there are a lot of things that need work, such as the paving stones here. My main aim at the moment is to do some of the cobbled lanes and gutters around here – lots of squarish stones there, too many to sculpt really. I think displacement would be quicker, as long as it works properly. I must admit a lot of the time I spent on this was getting the vegetation correct, which wouldn’t be much of an issue with a gutter or lane.
