If only there was a way to scan and auto-generate from background image(s). Pardon me in case I've already posted this suggestion. So many sliders, gauges, etc...
There was a guy who worked on a project with generating from a set of photos. Unfortunately he chose a very restrictive license making it largely unusable in an open source context. There was a forum thread a while back, but I can't find it right now.
There is nothing of the kind in the MH software as such though.
So late to continue, but thanks for the response. Now is there any way I could make a personal request? I'd post it as a private message to someone trustworthy.
