Hard Surface Modeling - Sculpt or don't sculpt

13
So what's your preference? I've focused more on organic models than ever hard surfaced ones, so I'm having some issues finding out what is the best way to go about it. I've found that sculpting doesn't seem to do it for me, and I'm going to be trying modeling it entirely rather than trying to sculpt it. But that might also just be me not being totally familiar with the sculpting tools available.

Do you prefer to build your hard surface models from scratch in programs such as max or maya? Or do you prefer to do it in sculpting programs? Is it faster or slower to sculpt? If you do sculpt them, whats your favorite tools in the sculpting program to get those perfect edges?

I'm very curious to peoples preferences here! If you have any favorite techniques you'd like to share, I'm curious to hear about them too!

    It's entirely case by case. Most of the time it's faster to do mechanical stuff in Maya/Max (with perhaps a quick weathering pass in ZBrush) but it depends on the particular shape you're trying to make. There are some forms that are very easy to create with Shadowbox that'd be a nightmare to poly model.

    If you're open to other apps as well, you might look at something like Rhino or Moment of Inspiration. CAD modeling has a lot of advantages for certain shapes with it's clean booleans and mathematically perfect surfaces.

    You can use the planar/clip brushes in ZB for sculpting, there's some pretty good kits out there like the Eat3d one showing how to sculpt hard surface - personally I prefer a mix, start in ZB and put some basic forms down with cuts/grooves where you want them, then retopo in something like Maya or Max and add loops for clean edges, etc.

    this sounds horribly inefficient. in a production environment you're gonna start with making a greybox blockout, which is a blockout that has all the main shapes and major details made already. to be honest, with hard surface modeling the hardest part is laying out all the shapes, so once that's done all you need to do is separate out the parts and start adding loops.

    using zbrush is a complete pain in a production environment where you will be told to make major design changes to the high poly while you're making it or even later in development (if your dumb art director wants to waste time just to look important to execs). this is sort of comparable to making a model house out of blocks vs out of clay; with blocks you can just move stuff around and it'll look right, whereas with clay you can do the same, but it requires a lot more work to make it look like it was made that way to begin with.

    imo with hard surface, zbrush should be reserved for final detail passes, if absolutely necessary at all. for most cases you're much better off sculpting some generic damage and saving it as generic normal map overlays--that way you can handle damage in photoshop quickly and skip exporting your model to zbrush, sculpting things, decimating the mesh, and finally loading it back into a program for baking.

    I like to do HS in 3DS Max, so I can make changes... quickly.

    If you really know and control the tools in 3DS Max well, it will be fast.

    a little of both I would say, really I think Maya and max are much more versatile for the mechanical, but then why not at the end of it import it to z and get some detail on.

    I still prefer traditional apps for making base meshes above all, dynamesh is indeed cool and powerful and z can do hard edges, but the much more technical toolset I think gives you good versatility.

    I think the best thing is not to take any piece of software off the table and to remove yourself of all prejudice, at first I just knew max, then I learned how to use Z, then went over to mudbox, then back to z where I really got in depth with it, then most recently I got into maya and god damn! I am really liking maya, and UV layout is craaazy good for UVs despite its terrible UI

    Ye agreed, majority of work will be in max/maya/modo, with some extra work in zbrush later.

    The only exception to this ive seen is some people doodling or exploring concepts in zbrush, then redoing it in max later. Not really a production pipeline, but could work to mess around with new ideas if you are designing stuff from scratch.

    i get into this debate quite a bit with a guy at work. he prefers to do all his hard surface in zbrush (after making a simple block in maya), whereas i do pretty much all hard surface modeling in maya. i think the differences really set in when you're doing a low-res (if its for a game model). Most times i can easily rebuild a game mesh off of my high res by either cloning it and deleting edges, or doing a create poly and snapping to verts on the high res. In most cases for a high res model done in zbrush you have to rebuild it entirely to make a game res, and loading a zbrush model in maya is generally a pain unless youve got good specs on your computer.

    No, not really. I've seen quite a few character artists create 'blockout' sculpts which is just a basic sculpt really roughed in, plotting where all the details would go, then they retopologize or model over that with final details. I find it a good way of laying down what you need quickly so you can try different ideas out, if you like it then great, it can be modeled in and finalized, if not then it can be scrapped - I just find it a faster process.

    Care to elaborate? If you're concepting/trying out ideas in 3D, would it not be faster to sculpt them out in ZB and if they're not working, chuck them and try other ideas, than to spend time modeling them out in detail, realise they don't work and have to take ages modeling something else? Or would it be better to go "Oh well, I've spent 1-2 hours modeling this now and it looks 'ok', might as well keep it"

    is it faster to sculpt it than to make simple shapes from primitives? probably not. besides, in production it's usually not the 3d artist's job to try major forms out.

    also, if you're making a very large and detailed hard surface item like a vehicle or gun (read: not character accessories), there is no point in blocking something out--only to scrap it and make it all over again. it is better to start with a relatively detailed blockout in max that you can use as a base when doing the real modeling.

    even better would be to have your concept artist paint over a simpler 3d blockout (PLEASE DO THIS FOR THE LOVE OF GOD), then send that simple blockout to the 3d artist who details it a bit more, gets it approved, and can use that as a base to start the high poly.

    Racer445, I think what you say is true for the specific examples you bring up, weapons and contemporary vehicles.
    But when you're doing some more "sci-fi" stuff, like mechs, or semi-organic armor with hard surfaces pieces, sculpting in Zbrush is really fast, and it allows quick iteration if the concept art isn't so well defined (which is often the case depending on where you work, unfortunatly).

    I use both techniques depending on the object I need to produce, but more and more I turn to Zbrush to quickly mesh out shapes and proportions as it feels much faster and pleasant to work with sculpting tools rather than push points around (which doesn't mean I won't sometimes finish it in sub-d modeling later on, again totally depends on the piece).

    More often than not, the hard surface work I see from zbrush is sub-standard. I think this is because the people using zbrush for hard surface work aren't as invested or picky about the quality of the models. What I enjoy about hard surface work are really confident/strong forms with clean and deliberate contours and edges. Making a complex surface perfectly regular and convex with clean, well controlled edges is extremely difficult to do in zbrush. I would love to see someone capable of doing a high end model of a production car in zbrush but I think that is close to impossible.

    I will say, traditional modeling is the best way.
    1) the file is lighter
    2) much more precision/control
    3) you dont need retopo (huge task! dont trust in autoretopo tools)
    4) in the end you can import the model in zbrush/mudbox/blender and add the amout of details that you prefer.
    5) your model even is at blockout stage, is ready to be rigged for animatics.

    Zbrush of course is really good for concept artists and for hardsurface that maybe dont need to be rigged and animated.

    goodluck!

    Just to chime in..yeah, I'm on the regular max or maya methods, it's just fast, more production friendly and just works. What Alec Moody said about cars and racer445 said is my thoughts exactly.

    But I can see maybe if your doing a highly organic designed hard surface model where mudbox or zbrush might actually work better especially due to how hard it can be to control loops on curved surfaces and have tons of detail with no floaters.. But even that stuff is still doable in Max or maya no problem it just takes skill. Plus there is always photoshop to fall back on for now with panel detail etc. there are lots of other areas though where mudbox and zbrush exels for instance doing ornate wood details, or metal carvings etc. it depends on the type of work and design.

    Damn for once I'm going to have to disagree with Racer. I do almost all my hard surface in zbrush these days, most of the Rift work I did was all ZBrush hard surface. It works really good for organic hard surface but for stuff like cars and guns and stuff yeah I'd probably start with a blockout in Maya or Modo. Also when doing hard surface in zbrush when I need to retopo a piece I just retopo it real quick in zbrush and apply some creases to the new low poly. Sometimes importing/exporting to another program just takes a bit too long for each piece I come up with from a bunch of spheres.

    I think this topic causes some debate because of one major issue.

    Designing a new character or weapon or vehicle etc is not the same as making a nice clean hard surface model. Those are 2 very different jobs, usually done by 2 very different people within the same studio in my experience.

    It seems like a lot of people on here, including me, would like to do both concepting and modelling at the same time and go straight from zbrush blobby design to retopo and hardsurface, which is fine at home but most likely wouldnt work so well in a studio environment where the management may ask for changes and redesigns at any point.

    I agree with Ged.

    Zbrush is great for quick, stream of conscious concepting without artwork, but I can see how that wouldn't work in a production environment wher ethe concept art is provided. I generally start with a mesh from Maya, using the crease tool to keep corners crisp without adding loops so that Zbrush subdivides evenly.

    BUT, I have to say that ZBR is making it a lot easier to do hardsurface. The "Polygroup by Normal" - "Crease by Polygroup" one two has been my go to workflow for any sculpt, hard or organic. Super fast and easy to do/undo. The Hpolish, Clipping and Trim brushes, and Panel loops as well.

    Anyone worried about bringing their sculpts back in Maya/Max, decimation master works extremely well especially for hard surface sculpts. In fact, they would recommend it because it keeps cornered edges really sharp if needs be.

    modo is not the best example for sculpting... i don't recommended it. Zbrush is the way to go.

    And by the way, All depend of the purpose. If i need to do a high poly subdivision model for animation, i won't be using Zbrush, it's of common sense for me (i don't like to waste time stupidly in retopos). BUT, if i'm doing something for game art and i need it as fast as possible, i won't care about topologies, nor about polygons. For too many assets i use sculptris... sculptris eh!

    Ged put in my thoughts exactly.

    If you're at a high budget studio working with strong concepts for precise material like guns and vehicles, subd is the safest and most direct route. Imo. If it suits your skills & workflow.

    My stance on game art is to do whatever works, and in less restrictive or smaller teams, that also amounts to doing whatever you /want/. Especially if you're indie or working with looser concepts.

    I mean. An aNet artist once mocked me for "still doing subd"... just a means to an end. Their 3d artists just happen to be the ideal game artists with the concept, sculpting, modeling, and texturing skills & sensibilities to finish their own shit. That's the way I like it, personally. Trust your artists' competence levels and they'll not only deliver (or not), but also grow more rounded in the process.

    Unfortunately, the sculpting tools didn't change for better, they are still the same :(. They did some minor UI changes and they added pixar subdiv as much. But at the end, what really matters, the perfomance is still very bad, as bad or worse as in 302, 401, 501, 601. With each version of modo, the viewport perfomance drops, and the application launch passed from click/program opened to click/wait like with photoshop launch. Modo 701 is overbloated.
  • dazzerfong
    Personally, poly modelling works for angular stuff like guns, knives and (maybe) mecha. However, once you go into curves and all, it's a pain in the ass if you poly model. I would know, since I'm modelling out every detail on a personal armour I'm working on.

    317€ for the upgrade, that's almost what i paid for modo 301 in another sale :poly122:

    And i don't use the sculpt, nor the rendering, nor the bones, nor the animation, nor the painting, nor the particles... just only the modeling and UV mapping features :(

    I wouldn't care paying less for a lite version (for what i will use), but as fast as modo 302 in viewport perfomance. With all the scripts i use i have more than enough right now. there's no point upgrading, but thanks anyways. I tried the trial of modo 401, 501, 601 and a few months ago the one for 701.. and i disliked it.

    Epic games uses zbrush for a lot of hard surface things. You can see some of their workflow outlined here. (Scroll down and find the videos by epic games.)

    A lot of the hard surface stuff for the infiltrator demo was done inside of zbrush with retopo in max + alphas for detailing. In fact the statues were even posed after using decimation master and then finalized after that.

    As everything moves towards realtime booleans though I think that will be come the preferred method for hard surface modeling.

    Modo seems to be the furthest ahead in achieving this. But before everyone jumps in about clean topology lets remember that if you're baking a normal map and it's hard surface that you probably shouldn't care anymore as long as it looks good. :)

    I think we're getting very close to a paradigm shift in modeling. One which I can't wait for it to arrive. We've been stuck modeling in the same manner for far too long. I can't wait until hard surface has a revolution similar to how zbrush changed organic modeling.

    100% agree! I think we're right on the cusp of something great, like a huge sweeping change in how hard surface modeling gets done. Whether it ends up being like Modo's MeshFusion or something else, I think it's definitely due.

    The tools in brush have really come a long way for hard surface imo. But it's very task dependent so I like to get into some hand retopo as soon as I have a good overall shape. (sorta like sewly's work flow)

    For me, the game changer is dynamesh. In some cases it really speeds things up to block out in z-brush instead of vert pulling because it's just so much faster. If you're blocking out in maya, and then going to z-brush, you've missed the point entirely!

    It's really important to distinguish hard-surface Zbrush work done by improvising funky shapes with the various powerful yet hard to predict toolset, from hard-surface work requiring one to follow precise blueprints in a production environment.

    I think that most of the confusion in this thread comes from this. But at least, Zbrush/mudbox can be useful at the blockout stage of both.

    Yeah, if you need to follow something very precise from the start then zbrush is not an ideal tool since everything needs to be eyeballed.
    Going from a block out to finalized/perfectly clean hard surface model entirely in zbrush isn't a good idea at this point in time.

    I find that using predictable brushes instead of the fancy tools that are hard to control gets me a lot further, faster. (just inflate/flatten and H polish with some trim dynamic are really enough to get a solid blockout for fast retopo.) The advantage here is that you have something much quicker to show your AD and get feedback on before you invest a lot of time into getting proper topology and clean edges.

    This is all true, but these inconveniences can easily be offloaded to outsourcing or less senior staff.
    I think zbrush hard surface modeling will definitely upset the scene in a similar way as it did with organic modeling, but not necessarily in a good way.
    At some point, a job as 3D artist might be basically a glorified retopo position where you will be cleaning up and rebuilding hard-surface zbrush models to make everything nice and tidy, then hand it to outsourcing for the lowpoly and baking.
    Making a decent looking hard-surface zbrush "concept" doesn't take much longer than doing it in 2D. So studios will be getting those from off-site high-profile 3D concept designers, leaving little creative input for the actual studio positions.

    It can make the modeling process much faster and streamlined, but, as you said, at the expense of a tidy pipeline and creative ownership for many professionals.
  • WarrenM
    So you want 3 stages now instead of 2? Create in ZBrush, re-create using sub-d, then outsource the low poly? Yikes...
