What Is Custom 3D Sculpting, and Where Can You Use It?

Custom 3D Sculpting

In the vast landscape of 3D design, digital sculpting emerges as a distinctive yet underexplored art form, providing unparalleled depth and realism. While 3D modeling often takes the spotlight, the art of custom 3D sculpting carries unique strengths, bringing a tactile and organic touch to the digital realm. This guide aims to unravel the intricacies of digital sculpting, shedding light on its advantages over conventional modeling and navigating you through the possibilities it holds. Whether you’re delving into sculpting or seeking a proficient 3D sculpting company, this comprehensive exploration will be your compass in the realm of three-dimensional artistry.

WHAT IS 3D SCULPTING?

3D sculpting is the process of creating a 3D model through “pinch and pull” methods in specialized software. Just as a regular sculptor would take a block of clay and manipulate it until it gets the right shape, a digital sculptor will work with a computer, mouse, and virtual materials to create a 3D asset. In other words, it creates the geometry of a 3D object, but the model is only complete in the following stages, when color, texture, and other features (like rigging, animation, and VFX) are added to it.

3D sculpting vs 3D modeling

On the surface, 3D modeling and sculpting seem similar. Both can begin with the creation of a digital mesh (a patchwork of connected polygons/shapes). However, this is where the similarities end. Modeling is focused on adding, moving, and otherwise modifying lines and angles. It involves an adherence to geometric shapes and congruity, whereas sculpting is more flexible.

Custom 3D Sculpting

Sculpting is mostly focused on deforming lines and shapes, thus adding more detail, irregularities, and unique characteristics. For instance, special brushes can quickly turn an oval shape into a face, pulling small strips of material for the eyebrows, making indentations for the mouth and nostrils, pinching and collecting material for the nose, etc.

When we explain 3D modeling and sculpting, it is also important to mention that sculpting in 3D can be achieved without a polygonal mesh in a process known as voxel-based sculpting. Instead of polygons, the model is divided into voxels – pixels grouped together to create three-dimensional geometry and volume.

In the end, sculpting and modeling are two sides of the same coin and can often be used together to great effect. For example, an artist may use modeling to create the basic shapes of an object, then switch to sculpting to add all the fine details.

What are the benefits of using digital sculpting?

Depending on how you use it, 3D sculpting can shine or disappoint. You may get the model of your dreams in a matter of hours or spend days working on it with little progress. To make the most of your time, you should be aware of the strengths and weaknesses of this approach:

Pros:

  • Great for crafting organic objects
  • Allows broad freedom in manipulating the object
  • Easy to add fine details
  • Corrections can be added quickly
  • Often faster than modeling

Cons:

  • It is not ideal for creating models large in scope
  • Not suited for even shapes and geometry
  • Requires a rare set of skills
  • Brushwork can be hard to learn

WHERE IS 3D SCULPTING USED?

Though the artsy nature of sculpting makes it a popular hobby in the design community, this approach has plenty of real-life uses, especially for businesses.

3D printing and manufacturing

3D printing and manufacturing both require a high level of precision and detail in design. Since sculpting is known for its substantial detail and volume-focused dimensions, these designs are relatively easy to produce with physical materials. Thus, it is common to see 3D sculpting for 3D printing apply these assets in the form of blueprints for models produced in a factory or printer station.

Media

3D models are used broadly in media, from movies to advertisements to entertaining videos. Some people associate the process with a sculpture and think that the models created with this method are static and unmoving, but this is hardly the case. The truth is that many of the animated and moving 3D models we see in media were once 3D sculptures that were eventually rigged and put in motion.

Gaming

This one is a no-brainer. Gaming is the perfect spot to use sculpted assets, because games are filled to the brim with the type of objects that are usually sculpted – characters, creatures, foliage, and accessories. For example, the model of the Murloc Warrior designed by Program-Ace served as one of the game’s enemies after it was integrated into the software.

Advertising

As we have mentioned, the sculpting approach is helpful when you are working with irregular and often incongruent designs. Advertising often seeks to draw attention through the mysterious and unusual – objects that catch people’s attention, so the two often go hand-in-hand. That is why you can often find sculpted heads and faces on billboards and posters, sometimes added to clips. On the other hand, the design technique can also grant beautiful and uniform models of whatever is being sold.

Product design

During prototyping and product development, sculpting is generally used for pathfinding – establishing the outward look and general design of the product. It is also used for prototype manufacturing of items with a relatively simple design. Because such assets cannot include functional internal elements and components (as opposed to assets created with modeling), the approach is not a good fit for designing machinery and equipment.

HOW TO START 3D SCULPTING

Before you create your first sculpted model, you should get a feel for the process and learn some of the conventions present in the art. Let’s examine the key aspects.

Process

As you would use a glob of clay in real life, sculpting digitally starts with a formless mesh that is then pulled in all directions to create the basic form of your object. This is done with different brushes, each of which uniquely manipulates the material. For example, some of the most popular brushes include:

  • Curve brush – creating curves and indentations
  • Clip brush – cutting away excess materials
  • Smooth brush – turning rough and textured surfaces smooth
  • Groom brush – modifying fiber-based objects like hair
  • Curve bridge brush – fixing and melding bridges between curves

Iteration has an important role in sculpting and works through layers. The base layer of a sculpted design will include the basic shape and outline of the object, while further layers will add more detail and features. For example, the lower layer of a character may be their body shape, while the upper layers include clothing, accessories, etc.

References

Unless you are creating a new design directly from your imagination, it helps to use a reference during sculpting. In terms of general appearance and details, you can use photos, sketches, and clips. You might even benefit from a physical model of the object you are creating since you will be able to feel its textures, look at it slowly from all angles, and learn everything there is to know about its appearance.

For example, for the crab model pictured below, we used concept art as the main reference but also used a similar-sized action figure for a reference of the character’s posture.

You can also follow one of the top 3D sculpting tips and save time on your design by turning references into a rudimentary 3D model. For example, a set of photos from different angles can create an object in multiple dimensions, while a scan can capture detail and form even more accurately. With these advanced references, you might only need to make minor adjustments.

TYPES OF 3D SCULPTING SERVICES

If you lack the experience, time, or resources to create your own sculpted models, you can opt to order services from designers and providers locally/on the web. Most art studios will offer selections or variations of the following sculpting targets:

  • Character: 3D character sculpting is today’s most popular and in-demand service. Due to the complexities of character design, it can take weeks to create a high-poly character model and days spent on only 3D face sculpting, but at least the technique will offer the most ease and flexibility in the process.
  • Hard surface: Surfaces and environments are more often covered through modeling, but sculpting is also a valid choice if you want to add great detail and irregular textures/features to the assets. Even low-poly environments may be well-suited to this technique if they include numerous uneven shapes and many broken lines.
  • Props: Props can be created alongside 3D body sculpting (e.g. the mythic artifacts held by the Murloc Guardian) or as an entirely separate design. A good design will have plenty of texture and structural soundness, adding realism to the unique world of the model.
  • Product: You can certainly create digital sculptures of your product as an alternative or supplement to modeling. This is especially useful during prototyping when you are still working on the final design and want to play around with some minor changes.
