Most* production workflows in games, don’t use retopo tools, I’d say. Seems the norm’ to work from a concept in a 3dediting programme. But I can see in fields where visualisation is more of a factor that it would be a big plus. Which considering Mudbox2009 seems to be aiming for that market it’s very odd that it doesn’t include retopo tools.
3dcoat - Nemomiod was saying the great advantaged of 3dcoat, I just wanted to add that it’s path and marquee tools are superb for creating hard surface-like details. Something which is hard to do in any other sculpting tool. Great for so adding details to though normal maps.
On the downside I loathe it’s sculpting tools and it’s brushes. Not being able to change subd-levels is a head turner for me. Vers. should address these issues.
I tested the Mudbox 2009trial It’s really unimpressive for new tools. It lacks a lot of tools you’ve come to rely on, like the lazy brush. Tho the tools it does have seem to be greatly improved, the pressure and control just seem heavenly to use. The feel of the brushes really is amazing. And of course the super high resolution models you can get. On my machine I get about twice the polycount compared to Zbrush 3.
