Ah, I see. Eloi suggested that method of displacement a while ago and while it seemed pretty interesting, I tested it and ran into some issues that led me to pan it as an officially supported method....the main one being that the reverse displacement applied to the subdivided slice cap faces can lead to a lot of nasty mesh self-intersections and other artifacts. Also you can't get clean non-overlapping convex hulls from the result when not doing displacement as a post-effect, so putting the result in a PhysX sim has issues...although I guess that would be the case for the CSG method as well, so that problem itself is not a dealbreaker.
