(since i have you here, can 3DC do this?)

zbrush does this.

yep, but 3D-coat?

I thought 3DC had something like this too.

Very cool video. I like the 'backlit' surface he used to see the imperfections.

3dcoat can do hard surface. Dave isn't using any special tools for that sculpt in mudbox... he even says so at around 34:34. Even without the new polish brushes in 3.5 I've sculpted hard surfaces in ZB in the past too. The new brushes just make it easier for some things. It's really on you as an artist to be able to do this stuff, not the program.

I know one thing that DOES help when working in 3dcoat and voxels is their boolean nature, which allows you to create any forms you want out of thin air, with no need for modeling polygon base meshes first, or getting polygon stretching if you try to deviate too far from your original shape.

Here's a WIP of a hard surface piece I'm working on in 3dcoat in my spare time:
http://www.dropbox.com/gallery/92176/1/PowerArmor?h=1e2019

Mostly just used the build brush and swapped the alpha for it from a sharper to a smoother gradient as I needed. Lots of smooth brush to tighten up the planes around corners, but no special brushes other than the copy brush, to lift pieces into new layers.

There's a lot of separate pieces rather than just one big one, which makes little sense to do when you are building more complex technical or machined parts. So I started big... just a few pieces, then broke them up or copied parts from them as I went. Again, a major strength of 3dc over polygon sculpting tools. Haven't decided where I'll finish this one though... might even old school it and finish it in silo, using the retopo as a base as I want a final piece that I can animate for renders too.

3dc doesn't do the vector displacement map trick with the ear though. I don't really see it as a big deal. It's definitely not a selling point of mudbox 2011 for me. Sure you can use it to make a new ear on a sculpt... or any number of things. I can do the same thing in 3dcoat, just merge an ear mesh from outside the scene, and have it seamlessly merged onto a head as if you sculpted it there, since voxels can be merged together from different layers into one. Same result, different approach and no more work than with the VD map. Modo does VD maps too and it never really pulled me into the app for sculpting when it was added more than 2 years ago.

3dc's weakest aspect right now is that voxels are more of a resource hog than polygons, so performance suffers as you go into higher detail levels. I've found things to be pretty smooth though by working in smaller, more manageable chunks spread out over more layers. For this reason I tend to use it mostly for blocking out sculpts and building them up to a medium to high rez state. I can finish them in zbrush or move over to the paint room and add details into the normal map instead.

Really great!

Yeah, that's good. I played around with zbrush's new hard brushes but I'm not anywhere near that comfortable with them yet.

meh, dirtbox is just a poor zbrush wanna be app... :)

nah, ZB has more features, but MB is faster to work with for basic things.

i'm jumping on the 3D-Coat train though
(not because of price, but because of features and Voxels)
3D-Coat will always have a speed increase anyway for each time i upgrade the computer (CPU/GPU)

some interesting comparisons,
Mudbox $750
Zbrush $600
3DCoat $235

why MudBox is on top here is beyond me though...

it looks to have import/export though... (but maybe not stamp?)

awesome stuff James!

I haven't gotten the hang of hard surface modeling in Zbrush myself, but I've seen some really impressive stuff with it, this one is really nice: http://www.zbrushcentral.com/showthread.php?t=69967&page=13&pp=15

I laughed when I saw the "lazy mouse"... As much money as Autodesk brings in, they seriously can't at least put a little effort into making it appear as though they didn't directly copy something...
