Digital 3D sculpting is a more intuitive form of 3D model creation that suits artists coming from a traditional sculpting background. If you have ever played with clay it is not dissimilar. It is useful for creating organic form concepts and 3D objects for artistic reference. Some software allows you to paint onto the created model as well.
Generally models made using this method have a very high polygon count the more detailed the model is and have to be retopologized or lowered in resolution and optimised for texturing for use in game engines (I have virtually no experience of this process yet but I’m learning), but it is generally useful for artists and illustrators as is. In any case before getting into retopology you have to create your model somehow. I’ve put some links to better explanations about retopology for you at the end of this article if you are curious.
Here are some free and commercial software options for digital 3D sculpting. The different software all have their own features, pros and cons, but I’m not really going to go into detail in that regard as I haven’t used all of them. The ones I’ve tried so far are Blender, Sculptris, SculptFab, Sculpt GL, Dilay (now discontinued) and 3D Coat.
Blender is a powerhouse of a program for 3D modelling and it also supports 3D sculpting. There is a high learning curve to using Blender for beginners to 3D modelling as I have experienced myself, but if you have the patience to learn it you will get hooked. I’m only just getting to the 3D sculpting, but it is fairly straight forward and there are some good online tutorials around.
Sculptris is a free 3D sculpting application which is developed by Pixilogic who also make Zbrush. It is a good introduction to 3D sculpting although no longer actively developed. There are now several other free alternatives to Sculptis which arguably have newer features.
Sculptris has been replaced with ZBrush Core Mini. Sculptris features were imported into all of the paid versions of ZBrush as well.
Meshmixer is a bit like a 3D pocket knife tool. It can be used to kit-bash 3D objects together and it also has basic 3D sculpting features. It might be useful for creating base meshes for use in other more dedicated 3D sculpting programs. It also has features useful for 3D printing.
This experimental software is designed to be intuitive for artists. The creator of this software has made some amazing models with it and the next version of it will have sculpting features and improvements, so it may be one to keep an eye on.
This is very easy to use and if you are completely new to the concept of digital sculpting this will get you up to speed right away. You can use it in your browser without any need to install software on your computer. It is developed by Stéphane GINIER who is also developing Nomad for mobile digital sculpting.
SculptFab is developed by the same people that do SketchFab and looks like an improved version of Sculpt GL. It has dynamic topology features.
It does sculpting, UV mapping and texturing. There is a pro version as well if you donate $2 to the creators email.
Rocket 3F does a bit of everything, but it also has 3D sculpting features. It is designed to be easy to use for artists and designers who want to create concept art. You can find out more about it on their website.
I’ve heard a lot of good things about ZBrush from other artists and Illustrators and I did buy the student/ amateur version of 3D Coat several years ago which was within my budget. It can also be used for texturing and has retopology features so I may look into it again soon now that I have a better 3D workflow knowledge after learning Blender basics from CG Cookie, YouTube and Udemy courses.
There is a high learning curve to the more powerful commercial software to beginners to 3D modelling and sculpting. Some basic knowledge of 3D programs would probably help you. Lots of online training is available nowadays so don’t be intimidated if you really want to do it.
If you have the budget the following software’s are definitely worth looking into for professional use although Blender is turning into a great alternative for professional workflows, especially the upcoming 2.8 version.
This is the luxury option for digital sculpting. I used to just go to the website and drool over the art examples. If you really want to do digital sculpting and money is not a problem, this is one to get. They have professional licenses and educational licenses available. There is also a much more affordable stripped down version called ZBrush Core and a free option called ZBrush Core Mini.
I saved up and bought ZBrush this year. I absolutely love this program. People say the UI is not to their liking, but I haven’t had any problems with it personally. You just have to spend some time learning it like anything else and then it becomes quite intuitive to use.
3D Coat has 3D sculpting and PBR texture painting features. It is very powerful. I own this program, I really like it for the early stages of sculpting and it is very good for UV unmapping and painting.
There is going to be a new version 2021 soon as a paid upgrade from version 4.
Mudbox has sculpting, painting, retopology and dynamic tessellation. If you are a student you can get it free for 3 years.
It has a strange name, but Silo is 3D sculpting software. It has has had a recent update. They are currently working on a new version which has an open Beta signup you can find on their website at the time of writing this.
Curvy 3D 4 has adaptive subdivision meshes for sculpting as well as curve based modelling tools.
I’ve got this program, it is useful for making base meshes for sculpting and has some great curve based features. The developer is very active in adding and improving features.
A new trimmed down version of Curvy 3D for beginners to 3D modelling.
Nomad is a mobile sculpting app. I’ve heard really good things about it, even comparing it to ZBrush for some of its features.
This is a commercial 3D software that like Blender does a lot of different things for a complete 3D workflow. It also has digital sculpting ability.
This is in free open Beta at the moment but is being developed into a commercial software. It is designed to be intuitive and easy to use for 2d artists who want to use 3D and are already familiar with software such as Photoshop. One to keep an eye on again.
