The big Blender Sculpt Mode thread (Part 1)

:grin: You probably know the drill of never being finished customizing ZBrush. I’ve spent countless hours shifting buttons and sliders in order to achieve the ultimate custom UI to end all ZBrush UIs, and still the next session I started shuffling the tools again. :grin:

@Musashidan, no need to defend ZBrush. :slightly_smiling_face: I know and acknowledge its brilliance. It’s just that Blender excites me more these days. For really high-poly sculpting there’s still no 3D editor that can beat ZBrush, but in my personal case I’m a modeler of highly stylized characters and scenes, so Dyntopo and Sculpt Mode in general are more than sufficient for my needs.

By the way Dan, did you read that Blender (at least Sculpt Mode) has just received a significant speed upgrade ? It’s still not ZBrush, I know, I know, but the Blender devs are working hard. :slightly_smiling_face:

Nice! You can already do this using an alpha image, raising the brush Spacing value and activating Rake to make the stitch texture orientation follow the brush stroke. But Pablo’s new function is much more convenient.

I recently did some more tests with adaptive voxel remeshing. I did manage to get it to work pretty well, but the size value is extremely sensitive and found that best results occur between values of 0.01 and 0.05.

What could be done is remap the values to make finding the sweet spot easier, because it’s not yet practical to make the adaptive part highly aggressive because of skinny triangles and concave faces.

I own 3D-Coat as well. One of its main attractions to me was Autopo, 3D-Coat’s auto-retopology tool. I wanted to see if it could match ZRemesher (Autopo already existed before ZBrush QRemesher / ZRemesher if I’m not mistaking). Autopo can compete with ZRemesher, as you can read in a comparison I once wrote.

3D-Coat is also a very competent sculpting tool, offering some things that still are not easy to do in ZBrush, such as simply digging a hole through a model, and clipping any shape without the odd artifacts that ZBrush can have after clipping. 3D-Coat also offers a lot more primitives than ZBrush, that are also more customizable than the ZBrush primitives.

And unlike ZBrush, 3D-Coat features great spline tools. :ok_hand:

I sculpted this in 3D-Coat a few years ago (rendered in Keyshot):

There are a few things that personally keep me from adopting 3D-Coat as my main sculpting tool:

  • The feel of brushing isn’t as fluid as ZBrush or Blender Sculpt Mode. It’s hard to explain, but it feels like you’re sculpting with mud instead of clay. I guess that’s partly due to the nature of the voxel-based approach, although ZBrush pixols are essentially also voxels under the hood.

  • Most people prefer 3D-Coat’s more conventional UI over the idiosyncratic ZBrush UI, but already being a ZBrusher before 3D-Coat made 3D-Coat’s UI a bit cumbersome to me. Lots of large drop-down menus and submenus filled with extensive tool labels, and separated workspaces for sculpting, painting and more. I couldn’t really get used to it.

Having said all this, 3D-Coat is definitely ranking very high among the available sculpting tools, and it’s much more affordable than ZBrush. Also, I should mention that 3D-Coat has a powerful alternative mesh-based sculpting mode that’s comparable to Dyntopo.

But personally, I’m going to stick with Blender and our friend Pablo, injecting my veins with new Blender alpha versions every day. :slightly_smiling_face:

I totally agree. The elitist industry giant attitude of Pixologic is being undermined by the sympathetic, open community of Blender, which is becoming a force to be reckoned with. Pixologic has got a well-oiled publicity machine and some of the world’s best sculptors use the brilliant ZBrush, yes, but anyone can see that Blender is an unstoppable rocket that’s causing a very interesting ripple in the commercial 3D landscape.

For example, compare the new ZBrushCentral forum with the Blender Artists forum. BA is a joy to visit because of so many engaged Blenderheads communicating with each other, helping each other out, writing tips and news, and so on. There’s a lively social atmosphere here, while the new ZBrushCentral feels cold and empty compared to BA. The new ZBrushCentral is very artwork-centric, it feels like one big ZBrush commercial, but not as a lively community where developers and users engage in fruitful conversations about the future of the software. I think Pixologic is sitting in an ivory tower, and Blender is a bold army of free-spirited knights that’s knocking on the tower door with more and more force. :slightly_smiling_face:

Is there a way to turn on cursor visibility while making strokes? To have same behavior as in texture paint and vertex paint.

I wonder what it would take to implement something similar to ZBrush’s polish tools. Specifically the “global” polish tools (ones that operate on every unmasked part of the mesh). Clay polish, polish by features etc.

Now that we have the new remeshers, I think a basic polisher sounds feasible (at least a barebones version). I assume the biggest technical challenge is edge detection. Once you know where the edges are it should be reasonably easy (*) to apply the new remeshers adaptively preserving hardness based on a setting and smoothing out the areas between. The less topology you leave between the areas, the smoother it becomes. A naive approach probably wouldn’t handle large curved surfaces but, especially if it supported only touching unmasked areas, could probably be used to quickly add polish to panels etc.

*) Easy in the grand scale of things, not easy as in trivial.

A polish tool that maintains volume and only irons out small inconsistencies is also very high on my Sculpt Mode wishlist.

I can do it in my sleep at this stage… :laughing:

That’s exactly how I felt when I first tried it, but it was never meant to be a replacement for trad DCC modeling tools - it’s an augmentation to that ecosytem I keep talking about. Its introduction gave us ultimate control over creasing, and more importantly, Polygroups.

100% I’m not proposing that ZB is perfect. There are a lot of areas that drive me crazy and I long to see overhauled - a proper scene Outliner and a Mudbox-esque sculpt/paint layer system, being my top 2.

This is something I fully agree with also. I’ve never met a single person post ZB 1.55 days that uses the pixol painting toolset. :slight_smile:

In all honesty, we all know that ZB was never intended to a trad 3D program. If it was going to go that route it would have back when Skymatter released Mudbox 1.0. It’s a case of people changing to the program’s paradigms if they want to use it, rather than the other way around. This is why ZBCore was introduced, to ease the learning curve for new users.

Definitely. I can see the potential for certain with Blender’s sculpt mode for cartoony/stylised work, but for high-end realistic work and hard-surface sculpting…nah :wink:

I don’t want to sound too negative because I see excellent potential in Blender as a sculpting program in the future. I am fairly new to Blender and I think it’s a wonderful program and there is nothing more I’d love to see than the Sculpting tools give me the power of ZB, but in a true 3D environment like Blender with full access to its excellent modeling workflow. However, it’s going to take a lot more improvements/features to drag me away from ZB.

I’m itching to get in a do some sculpts, but I just can’t get the navigation setup like ZB right-click nav. I’m so used to navigating in ZB that my brain won’t allow it. I have changed some settings on my Wacom and some of the Blender keymappings, but it only gets me 90% there, unfortunately.

I’m not defending it…it doesn’t need defending. :laughing: I understand, mate. Believe it or not, I’m excited too. :smiley: I can totally see why you would be more than happy with Blender for sculpting, considering your medium. I’m still going to keep trying Sculpt Mode because it has such great potential. It will never replace ZB for me, but with GoB I could certainly see myself using the posing tools, Cycles instead of Keyshot for lookdev renders during sculpting, and even maybe for quick edits or quick manual retopos instead of my usual Max workflow for this.:+1: Who knows? Either way, getting into Blender was an excellent decision for me and it’s only going to get better and better. The future is bright, my friend.

This! Would be pretty amazing to have autosmooth like options in blender. It makes stylized characters sculpting so much faster.

I’ve also been testing Pablo’s improvements, and loving the new Voxel Remesher. Here’s my hapless test subject, Suzanne:

Sorry but I’ve been wanting to use ZBrush for a while and I don’t know what’s multi-level sculpting, and can’t seem to find it. What do you mean by that? Is what blender calls multires?

Its called multiresolution modifier. But dont waste time. Its broken from like 2005 and never fixed.

Brecht and Pablo have both taken a look at the MultiRes modifier the last few months. I even posted news about it yesterday regarding the broken masking. https://developer.blender.org/T69956

I think it is just a matter of time that the bugs with MultiRes will get addressed, or we get a brand new subdiv system. Pablo and Brecht have been doing a lot of nice work in 2.81 so far and Sculpt Mode is looking very promising once the patch officially launches.

Subdivs are a pretty essential workflow for sculpting and a solid system for it will unlock some serious performance boosts. If we make enough noise about it we can hopefully get it bumped up to a 2.82 release.

Work is now being done on my report regarding the poor performance of QuadriFlow when used on high poly sculpts: https://developer.blender.org/D5958

Pablo also mentioned a MultiRes workflow, so the modifier is going to get looked at soon most likely. He’s even talking about making an automatic system where using QuadriFlow will add MultiRes and project from the old mesh at all subdiv levels in one process. That to me sounds super useful.

This afternoon, brecht pushed several commits that made new cursor working with multiresolution modifier.

Brecht also just accepted the revision on Pablo’s QuadriFlow patch. Just needs Jeroen to accept it and we will be able to test it as well.
