AI character design workflow: from concept to 3D character in Blender

Coming up with a character idea can take longer than expected. You sketch a few options, tweak them, start again, and only then think about how it might work in 3D. That early stage often slows everything down. With tools like GraphicsGen, you can move through that phase much faster, which is why the AI character design workflow is becoming more common.

In this guide, we’ll go through a simple AI character design pipeline, starting with GraphicsGen character design and moving on to a practical 2D-to-3D character workflow. Blender is now a force to be reckoned with in the world of 3D and is the tool behind award-winning cinematic experiences, such as the Flow movie.

By the end, you’ll have a way to take a concept from GraphicsGen character design and turn it into something you can build in 3D. This approach works if you’re just getting started with a 2D-to-3D character workflow, or if you’ve been exploring different ways to move from images into 3D using an AI character design workflow. So let’s dive in and be a part of shaping today’s 3D design trends.

TL;DR:
Begin with Envato’s AI graphics generator to sketch out a few character directions. Pick one and simplify it before moving into Blender. When building the model, keep the shapes clear and stylized rather than detailed or realistic.

AI character design workflow: What you’ll need

New to Blender? Don’t worry, we’ve got you covered! Check out our Blender Basics video below that covers everything you need to become a 3D artist.

Step 1: Preparing to generate character concepts

The first step in any AI character design workflow is generating ideas quickly. Instead of spending time sketching, you can use GraphicsGen character design to produce multiple character directions in minutes. This helps you explore different styles, proportions, and personalities early on, before committing to anything.

Write prompts that translate well into 3D

When creating AI graphics prompts, think ahead to how the design will work in 3D. This is key if you’re learning how to create 3D characters from AI images. Focus on:

• Clear silhouettes (easy to recognize shapes)
• Simple forms (avoid overly complex details)
• Stylized proportions (exaggeration works better than realism)

For example, instead of prompting for highly detailed textures or intricate clothing, prioritize shape and structure. This makes the transition from 2D to 3D character design much easier.

Step 2: Generating character concepts with GraphicsGen

At this stage, the goal isn’t to get a “final” design. It’s to build a strong foundation for your AI character design pipeline and set you up for a smoother 2D-to-3D character workflow later on.

Go to GraphicsGen and choose a style

Let’s start by logging in to your Envato account and opening GraphicsGen from your dashboard. Once you’re in, scroll through the available styles and choose Soft 3D Mascots. This style is a good fit for simple, rounded characters that are easier to carry into a 2D-to-3D character workflow later.

Write a simple prompt

Once you’ve selected the style, enter a short prompt that clearly describes your character. For this stage of the AI character design workflow, it helps to keep things simple and visual. For example:

“A cute soft 3D mascot frog with a round body, pastel green skin, small brown eyes, rosy cheeks, a simple smile, and a cream belly, sitting against a warm beige background.”

Generate variations and compare

It helps to try a few different versions of your character idea and review them together. This makes it easier to spot which designs feel clear, balanced, and practical to build.

• Strong overall shape
• Readable proportions
• A design that feels easy to build

This step is what makes the AI-to-3D character pipeline effective. You’re selecting a concept that will actually work when you move into modeling.

Step 3: block out the character in Blender

This is where your 2D concept starts to become a real 3D model. In this part of the AI to 3D character pipeline, you’ll take your GraphicsGen design and rebuild it using simple shapes in Blender.

Set up your reference

Once you’ve chosen your concept, open Blender and bring your image into the scene as a reference. This helps you stay aligned with your original GraphicsGen character design as you build.

1. Open a new Blender file
2. Delete the default cube if needed
3. Go to Add > Image > Reference
4. Import your character image
5. Place it in front view so it’s easy to model against (Numpad 3)

Start with simple shapes

When blocking out a character, begin with the largest forms first. In this stage of the AI character design workflow, you’re creating a rough version of the character using basic geometry. You can also use Toggle X-Ray (Alt – Z) to see through your 3D objects and use the reference image. This approach keeps your 2D-to-3D character design clean and easy to manage.

For a mascot-style design, start with:

• a sphere or rounded cube for the head and body
• cylinders or stretched spheres for the arms and legs
• small spheres for features like eyes

Use symmetry to speed things up

If your character is symmetrical, you only need to build one half, then use the symmetry modifier to duplicate it.

1. Model one half of the character’s features (eyes, arms, legs, etc.)
2. Add a Mirror modifier to each
3. Align the center line
4. Continue shaping the model

Step 4: refine the model

With the base shapes set, the next step is to improve how everything fits together. You’ll adjust proportions and clean up the overall look so the character fits together more naturally. This part is vital, especially if you want your character to appear more squishy! Want to know why you want to do this? Check out our article on why squishiness is trending in 3D and motion design.

Smooth and adjust the shapes

Work through the model and tweak the forms where needed. You might round out areas, adjust proportions, or shift parts slightly so everything lines up better.

• Use Object > Boolean > Union and then the Remesh modifier to join 3D objects together into one mesh (e.g., legs, feet, and body)
• Add a Subdivision Surface modifier for smoother geometry
• Use proportional editing to tweak shapes gently
• Scale and reposition parts to improve balance
• Then, Right Click > Shade Smooth to make your model look smoother

Define key features

Once the overall shapes feel right, begin adding your character’s main features. Focus on elements that define the look, such as:

• Eyes
• Mouth
• Hair or accessories
• Clothing shapes

Step 5: Apply materials and simple textures

Now that your model is in place, you can start adding color and surface detail. This step helps your character feel more finished while still keeping things simple within your 2D-to-3D character workflow.

Start with basic colors

Begin by assigning simple materials to each part of your model. You don’t need detailed textures at this stage; just flat colors are often enough, especially for stylized characters. Let’s start with:

• Select an object
• Go to the Material Properties tab
• Click New
• Choose a base color

This approach works well when following an AI character design workflow, as it keeps the look close to your original concept.

Adjust roughness to control shine

By default, materials in Blender can look quite shiny. For softer, stylized characters, you’ll usually want a more matte finish. If you want to dig deeper into texturing in 3D, check out our article on what PBR (Physically-Based Rendering) is in the world of 3D texturing.

To adjust this:

1. In the material settings, find the Principled BSDF shader
2. Locate the Roughness slider
3. Increase the value (e.g., 0.5–0.8) to reduce shine

You can also:

• Lower Specular slightly if the surface still looks too reflective
• Keep roughness consistent across similar materials

This small adjustment makes a big difference when following an AI character design workflow, helping your model feel closer to the original concept.

Step 6: basic lighting setup

Here, you’ll add lighting so the character is easy to see. A few lights are enough, along with a sun light to provide an overall direction.

Add a key light (main light)

This is your primary light source and defines how the character is lit.

1. Press Shift + A > Light > Area Light
2. Move it in front of your character
3. Raise it slightly above head level
4. Increase the Power (start around 300–1000W, depending on scale)
   Adjust the Size to soften the light

Add a fill light (soften shadows)

This light reduces harsh shadows created by the key light.

1. Press Shift + A > Light > Area Light
2. Place it on the opposite side of the key light
3. Lower the Power (around 50–200W)
4. Increase the Size for a softer light

Add a back light (separation)

This light helps separate your character from the background, creating a rim of light around the edges.

1. Press Shift + A > Light > Area Light
2. Place it behind the character
3. Aim it toward the back of the model
4. Set a moderate Power (100–300W)

Add a sun light (base lighting)

Soft sunlight adds an overall softness to the lighting and helps balance the scene.

1. Press Shift + A > Light > Sun
2. Rotate it so it shines at an angle onto your character
3. Set the Strength to a low value (e.g., 1–3)
4. Adjust the rotation to control shadow direction

Step 7: Add a background and floor

Here, you’ll add a simple background behind the character to complete the look. However, if you’re looking for something a little more complex, check out the links below for some 3D assets you can use to populate your scene.

Add the floor

A simple plane can act as both the ground and background, helping your character stand out more clearly.

1. Press Shift + A > Mesh > Plane
2. Scale it up so it sits underneath your character
3. Move it slightly below the feet

Add the background

4. Go into Edit Mode (Tab)
5. Select the back edge of the plane
6. Press E to extrude, then move it upward

This creates a plain backdrop behind your character.

Adjust the material

1. Select the plane
2. Go to Material Properties > New
3. Choose a simple color (neutral tones work well)
4. Increase Roughness to reduce shine

Keep the background clean and minimal so it doesn’t distract from your character.

Step 8: Add a camera and render the scene

With your lighting and background in place, the final step is to set up a camera and capture your character. This allows you to frame the shot properly and produce a clean final image.

Add a camera and frame your shot

To view and render your scene, you’ll need to add a camera and position it.

1. Press Shift + A > Camera
2. Press Numpad 0 to look through the camera
3. Press N to open the side panel, then enable View > Lock Camera to View
4. Move your view until the character is framed the way you want
5. Turn off Lock Camera to View once done

Adjust camera settings

1. Select the camera
2. Go to Camera Properties
3. Adjust the Focal Length (around 50–85mm works well for characters)
4. Enable Depth of Field (optional) and select your character as the focus object

This helps keep the character sharp and the background slightly softer.

Render your scene

1. Go to Render Properties
2. Choose Eevee (faster) or Cycles (higher quality)
3. Set your resolution in Output Properties
4. Press F12 to render
5. Once the image appears: Go to Image > Save As to export your final render

Before vs after: 2D to 3D

Now let’s look at both these creations side by side to see how the design has been carried into 3D and where small adjustments were needed.

Before (GraphicsGen concept)

This is your starting point, the original GraphicsGen character design that defines the look and feel of your character. At this stage, the focus is on silhouette, proportions, and core colors rather than technical accuracy. It sets the direction for your AI character design workflow, providing a clear visual reference to guide the rest of your 2D-to-3D character workflow.

After (Blender model)

This is the version built in Blender using your original concept as a guide. Here, the original concept has been translated into a 3D object, with adjustments made so the character works properly in 3D space. Although some details have been modified (such as the overall form in order to make this character easier to create), you can still tell that it retains the identity of the GraphicsGen concept. If you’re more confident with using Blender, you can, of course, modify the character even further or adjust the objects so that they fall closer in line with the original concept image.

Common mistakes to avoid

Here are a few common issues to watch for while building your character from a 2D image generated with GraphicsGen into a fully 3D creation in Blender.

• Starting with small details: Work on the main shapes first. Leave smaller features until later so changes are easier to make.
• Using shapes that are too complex: If something feels difficult to build, simplify it. Clear, basic forms are easier to adjust.
• Ignoring the overall shape: The character’s outline should be easy to recognize. If it looks unclear, adjust the larger forms first.
• Adding too many edges: Too many cuts can make the model much harder to work with, so keep the structure simple.
• Copying the image too closely: Some parts of a 2D image may not work the same way in 3D, so small changes are normal and help the model work better.

Pro tips for better results

So now that you know the 2D-to-3D character workflow, let’s check out a few tips to improve the AI character design pipeline.

• Think in simple shapes: Break the character down into basic forms. Building your character using objects like spheres, cubes, and cylinders makes it easier to build and adjust as you go.
• Keep proportions clear: In this case, using a large head, small body, and short limbs, etc., is a clear set of proportions that helps the character read well. Exaggeration often works better than subtle changes.
• Check your model regularly: rotate it as you work. This helps you spot issues early and keep everything balanced.
• Reuse what works: If you’re making more than one character, try to reuse the base shape for the next one. This saves time and helps keep your workflow consistent.
• Keep materials simple: Flat colors and soft surfaces often look better for stylized characters. You can always add more detail later if needed.
• Keep practicing using Blender: Now that you know how to create 3D characters in Blender, the more you practice, the more you learn, and the better your projects will turn out in the long run. Combining AI into your workflow can be a lot of fun.
