2D Image to 3D Character Model | Create Easy 3d Character Modeling

Introduction

Creating a 3D character model from a 2D image can be an exciting and rewarding process. In this tutorial, we will explore two different methods to transform a flat image into a dynamic 3D representation using Blender 3D. Whether you're an artist, a game developer, or a hobbyist, these techniques can enrich your 3D modeling skills.

Method 1: Transforming a 2D Image into a 3D Model

Prepare Your Image: Start by opening your desired 2D image in After Effects. Use the pen tool to create a mask around the object you want to model, effectively removing the background. Ensure that your masking is precise, as it's crucial for the next steps.
Rendering: Once you have your masked image, you'll need to render it. Use the following settings:
- Format: PNG Sequence
- Channels: RGB + Alpha
Choose a folder to save your output, and then render the image.
Using Google Colab: Open the specified website provided in the video description. Scroll down to the Colab section and click on the "Copy to Drive" button. Afterward, connect to a hosted runtime.
Upload Your Rendered Image: Go to the folder tab, find the sample images folder, and drag your rendered image into this folder. Copy the filename of your image and replace 'test' in the script provided.
Processing: Run the process by navigating to the runtime and clicking "Run." Wait for it to finish until you see the completion screen.
Download the Result: After processing, locate the result folder and download the 3D model file.
Importing into Blender: Open Blender and load the downloaded file to view your 3D model. Note that the model may not have textures initially.
Texturing the Model: Select the model and navigate to the UV Editing tab. Enter edit mode by pressing 'Tab', select all by pressing 'A', and then press 'U' to unpack the UVs. Open the rendered image to texture the model. Adjust the texture's scale and position to match the UV layout.
Finalizing: Add material properties to the model using the same image texture, and your 3D character model is complete!

Method 2: Using Online Tools

Accessing the 3D Generation Tool: Open the specified website and click on the "Try WebGL Demo" button. Here, you can upload a face photo for your 3D character model.
Customization: Select 'Head 2.0' and click 'Generate.' After a short waiting period, you’ll be presented with a 3D viewer where you can customize attributes such as hair style and color, as well as skin tone.
Downloading Your Model: Once you are satisfied with your adjustments, download the 3D model file.
Combining Models in Blender: After downloading, open Blender and import the body model (available from the provided link).
Joining Parts: Delete any unnecessary parts (like the existing head), then move and adjust your new head model to fit the body.
Final Adjustments: With both the head and body selected, press ‘Ctrl + J’ to join the models together, creating your new 3D character!

Conclusion

By following these two methods, you can effectively create 3D character models from 2D images. These techniques open up a world of possibilities for your creativity in the realm of 3D art and animation.
