3D Models: A Beginner's Guide
If you clicked on this article, you’re probably looking for a way to use 3D forms in your art. Maybe you simply need a bit of help achieving the level of precision that can be difficult to reach through traditional methods alone. While 2D artists can absolutely reach a high level through time and practice, 3D has become a powerful tool that many artists incorporate into their workflow.
That said, 3D is a much broader and more complex space compared to 2D. In this article, we’ll go over the basics of how 3D can support your work and how to use it effectively to elevate your art. After all, it’s not just about having the tool, it’s about having the skill to use it to its fullest potential.
Let’s dive in!
1. What should you use 3D for?
Before getting into the “how,” it’s important to understand both the strengths and weaknesses of 3D. For beginner artists, having a solid grasp of fundamentals is key before relying too heavily on 3D tools.
One of the most common uses of 3D is for posing references. Sometimes you have a pose clearly in mind, but it doesn’t translate well onto paper. A 3D model can help you solve this problem. Rather than searching endlessly for the right reference, you can pose a model exactly how you envision. Modern 3D posing tools are lightweight and user-friendly, making it easy to get results quickly.
However, there are downsides that are worth noting. Even though 3D models are flexible, they often feel stiff compared to real-life references. They lack the natural stretchiness, bendiness, and subtle movement of the human body, similar to traditional artist mannequins. Directly tracing a 3D model can result in stiff, unnatural poses unless you spend extra time adjusting it, which defeats the purpose of using it as a quick tool. Another limitation is proportion: most 3D models use generic body types, so if your character has unique proportions or your style is highly stylized, relying too heavily on 3D won’t give you the results you want.
Because of this, having a basic understanding of anatomy is still important. There are plenty of great anatomy resources online, my personal favorite is David Finch and Manga Materials’s YouTube channels. David Finch comes from an action comic background, I find his approach to the human body especially dynamic, even in still poses, his figures feel full of energy and life. And if you prefer a more technical approach, Manga Materials offers videos that clearly explain human anatomy, including how different body parts are constructed and connected. You can also check out the anatomy video and proportion articles available on this site, especially if you want something more directly tailored toward illustration work.
Once you have a solid grasp of the fundamentals, think of 3D as a base: you can always tweak and exaggerate afterward. Try to approach it like a sculptor rather than just mindlessly tracing.
With the character finished, you may want to move on to drawing a full background, complete with perspective, props, and environmental details, but struggle with placing everything at the correct angle or building a cohesive composition. This is where 3D becomes useful again. Using 3D models allows you to rotate and position objects freely, making it much easier to match your vision. This is especially useful if you need to repeatedly draw the same objects across multiple pieces, such as in comics or Webtoons. See example by Catbishonen.
A more advanced use of 3D is environment blocking and composition planning. Many concept artists use 3D in the early stages of creating large-scale scenes. By blocking out environments with simple shapes and quickly testing camera angles and lighting, they can generate multiple variations in a short amount of time. This is extremely useful for professional work, especially when consistency is required. A great example of this can be seen in Imad Awan’s video, where he demonstrates how even a scene built entirely from simple cubes can create a strong compositional base for paint-over. Later in the same video, he also incorporates photobashing, a technique that has long been used in the art industry, and with 3D software becoming more accessible, it’s even more powerful now.
With a clear understanding of what 3D can and cannot do, it’s up to you to decide how to integrate it into your workflow.
2. Resources for human proportions
2a. Clip Studio Paint
If you’re using Clip Studio Paint (CSP), you’re already saved yourself from the headache of which 3D poser to choose from. CSP has a built-in 3D tool along with a large asset library created by the community. Recent updates have made the 3D tools much more powerful, with features like Pose/Hand Scanner, texture painting right on the models, and customizable body types.
To use it, simply drag a 3D model onto your canvas, adjust the pose manually or load preset poses, then rotate the camera until you find your desired angle. Because it is integrated directly into your drawing software, it offers one of the smoothest workflows for quick sketching and paint-over.
When using CSP’s built-in 3D models, these are the controls you’ll use most often:
- Move/Rotate Camera: Orbit around the model to find your desired viewing angle.
- Move Object: Reposition the entire model on the canvas.
- Pose Manipulator / Joint Controls: Click and drag joints to adjust the pose manually.
- Body Shape Adjustment: Modify proportions such as height, head size, shoulder width, etc.
- Camera Angle: Specify camera angle from the preset.
Tip 1: The camera and perspective settings are often overlooked, but changing focal length can dramatically improve the dynamism of your pose.
Tip 2: For easy navigating, use the Left Mouse Button for orbiting the camera, Middle Mouse for panning, Right Mouse Button for zooming, and Middle Mouse Scroll to adjust camera focal length.
Best for: Seamless workflow integration
Pros: Light weight, and easy to use within drawing process, customizable poses
Cons: Models can feel stiff, some are paid
2b. Posemaniacs
I can’t recommend Posemaniacs enough. Unlike CSP, it’s more focused on learning anatomy than direct posing.
It features highly detailed muscular 3D models, making it excellent for studying anatomy and body structure. While you can’t directly modify poses, the site has a strong search and tagging system to help you find what you need quickly.
To use it, browse poses by category or search tags, then rotate the camera around the model to study the form from different angles. I recommend using Posemaniacs more for anatomy study and pose inspiration than for direct tracing.
Posemaniacs is simpler than a posing tool, but these functions are most helpful:
- Pose Search / Tags: Filter poses by action.
- Main Viewport: Rotate the model to study the pose from different viewpoints.
2c. Magic Poser
Magic Poser is a strong option for a free, lightweight posing tool. Its simplicity makes it very beginner friendly, with an intuitive UI and many preset poses.
To use it, start with a base model, then drag joints to pose the figure manually. You can add multiple characters or props into one scene, making it useful for planning interactions and group compositions. Once satisfied, rotate the camera to your desired angle and use it as reference.
Magic Poser’s interface is very beginner-friendly. Key tools include:
- Add Model / Add Prop: Insert additional characters or objects into the scene.
- Camera Orbit: Move around the model and frame your shot.
- Preset Pose Library: Load pre-made poses as starting points.
- Scene Lighting: Adjust basic lighting to preview shadow direction.
- Joint Manipulation: Drag body joints to pose limbs.
Best for: Quick pose setup
Pros: User-friendly interface that makes it easier for beginners, flexible posing
Cons: Limited features compared to other 3D tools (lacks many advanced options)
3. Resources for Environment and Props
3a. Sketchfab
Sketchfab is primarily a platform for 3D artists, but its massive library makes it incredibly useful for 2D artists as well. You can find almost anything, from realistic props to stylized assets.
To use it, search for the prop or object you need, then rotate the model freely in-browser to study it from any angle. It’s excellent for finding references of specific objects that may be difficult to photograph or search for traditionally.
Since Sketchfab is browser based, navigating through models is very straightforward and beginner-friendly. Simply type what you’re looking for into the search bar, you can browse through a massive library of models. From there, you can freely orbit, pan, and zoom around a model directly, making it easy to study objects from different angles without needing to install any software. This accessibility makes Sketchfab especially useful for quickly gathering prop and environment reference.
3b. Blender
Blender is a free, open-source 3D software with incredibly broad capabilities. Beyond basic modeling, it can be used for sculpting, rigging, animation, texture painting, procedural workflows with Geometry Nodes, and much more.
However, many of these features are far beyond what a beginner 2D artist needs. Because Blender is such a deep software, trying to learn everything at once can quickly become overwhelming and distract from your actual art goals.
For artists who simply want to use Blender as a support tool for 2D work, I recommend focusing only on the essentials:
- Basic viewport navigation: moving around the 3D space comfortably.
- Object transformation: moving, rotating, and scaling objects.
- Primitive modeling: building simple scenes with basic shapes.
- Camera setup: matching your drawing perspective.
- Basic lighting: establishing light direction for reference.
- Rendering: exporting your scene for paint-over.
These fundamentals alone are enough to build environments, block compositions, create custom props, and generate useful reference for your illustrations. Think of Blender as a giant toolbox, you do not need to learn every tool inside it just to hang a picture on the wall.
4. How to apply 3D models in your artwork
From here on, let’s look at some practical ways to apply 3D in your own artwork.
Example 1: Using 3D for Difficult Character Angles
I typically use 3D as reference whenever I need to draw an angle I’m unfamiliar with. In this case, it was a back view of the character, something I had very little experience drawing at the time.

To start, I imported a default 3D model into a blank canvas and rotated the camera until I found the angle I wanted. Since the pose was relatively simple, I skipped searching for pose assets and adjusted the model manually. For more complex poses, however, finding a pre-made pose close to your intended result can save a lot of time.
Once the model was posed, I began sketching over it and refining the body to better fit my style. Some artists go directly into lineart after posing their model, which is perfectly valid. Personally, I like to adjust body proportions and figure shapes during the sketch stage because I believe those details contribute heavily to a character’s personality. Default 3D models often feel too generic to fully capture that nuance.
From there, I proceeded with the rest of the illustration as usual, adding clothing, hair, and rendering. Having the 3D model as a base gave me a strong foundation to build upon and saved me a significant amount of time that would otherwise have been spent struggling with the pose.
Example 2: Modeling Custom Props for Accurate Design Reference
Fan artists will understand the struggle of trying to keep a design perfectly on-model. In this example, the character had a particularly unique shoe design that was difficult to find reference for elsewhere.
While in-game 3D models can sometimes help, they are often optimized for performance and appear low-poly, making them less useful as detailed reference. Because of that, I chose to model the shoes myself in Blender. Shoes are relatively complex forms to model, but with patience and online tutorials, creating a usable model is entirely achievable.

That said, before committing to building a custom model, ask yourself: How much will this actually help my piece? If you only need rough perspective and not exact design accuracy, finding an existing asset that resembles the object will often be faster and more efficient.
In my case, I planned to use the rendered model directly in the artwork and paint over it afterward, so investing time into modeling the shoes accurately was worthwhile.
Interestingly, 3D modeling is more similar to drawing than many artists expect. The process usually begins by blocking the object into simple forms, then gradually refining and adding detail. If the object consists of multiple parts, the workflow is simply repeated section by section: simple shapes first, details later.
Once the model was complete, assigning materials was straightforward. Since I planned to paint over the render anyway, basic flat colors for each part were sufficient. Lighting, however, remained important, I made sure the light direction in Blender matched the lighting setup in my illustration.
After finalizing the model, I imported my sketch into Blender to align the shoes properly:
- Add a camera to the viewport
- Match the camera dimensions to your canvas
- Enable background image and import your sketch
- Align the model to fit your drawing
- Render with transparency enabled
From there, I refined the render in CSP through paint-over and adjustments to better match my style.
Post-Processing Techniques I often use:
- Posterize: Simplifies realistic rendering into flatter, stylized values
- Gradient Map: Quickly remaps colors to fit your palette
- Overlay Layer: Softens and unifies render colors with the painting
- Paint-Over: Refines details and stylization manually
Example 3: Using 3D for Composition and Framing
3D can also be used less literally, as decorative elements or compositional framing rather than environmental storytelling.
In this piece, I intentionally scaled the 3D objects to enormous proportions in order to frame the central character and direct the viewer’s attention toward them.
What made 3D especially helpful here was that I began with only a vague idea of the composition. I wasn’t sure whether the concept would work visually until I started arranging objects in 3D space.
As I experimented with placement and scale in the viewport, the composition gradually became clearer. If something felt off, I could instantly reposition or resize it in real time.
Had I attempted this entirely in 2D, I would have needed a much more concrete plan from the start, and making adjustments later would have been far more cumbersome.
Example 4: Using 3D for Background Construction
This follows a similar workflow to the previous example, but here the 3D setup is used more directly for background construction.
Again, I prefer Blender for this because of its flexibility, though Clip Studio Paint’s 3D assets can work just as well depending on your needs.
One trick I often use for easier post-processing is creating two separate renders:
- Final Render Pass: The normal rendered image
- Masking Pass: A render where each object is assigned a distinct flat color
This makes selection in drawing software much easier. By using the Magic Wand Tool on the masking pass, I can quickly isolate individual objects thanks to the strong color contrast. This method saves time compared to exporting every object separately, two renders are usually enough.
5. Closing thoughts
This article is mostly intended as an introduction to 3D resources for artists. Now that you’ve made it to the end, I hope it has also given you a better understanding of how 3D can support your workflow as a 2D artist.
At the end of the day, 3D is just another artistic tool that can help you visualize ideas, solve problems, and speed up parts of your process. Whether you use it for posing, composition, environments, or simply experimenting with ideas, what truly matters is still your artistic decision making and understanding of fundamentals.
Start small, experiment along the way, and slowly figure out which parts of the workflow benefit you the most. Even a simple cube can become a powerful tool in the hands of an artist with a clear vision.
