Introduction to Befu HD

Befu HD is a multi-level framework that infers the 3D geometry of closed humans at a high 1k image resolution in a pixel-aligned manner, retaining the details in the original inputs without any post-processing. It is a powerful tool that allows artists and Creators to transform sketches into 3D models, opening up a world of possibilities for concept art and character design. In this tutorial, we will explore how to use Befu HD with a digital painted sketch and see what results we can achieve.

Process Overview

Before diving into the details, let's take a brief look at the overall process of using Befu HD. The key steps involved are as follows:

1. Preparing the Sketch: Ensure the sketch has a transparent background and readable human form.
2. Copying the Sketch to Drive: Save the sketch with a transparent background and upload it to Google Drive.
3. Connecting to Hosted Runtime: Connect to the hosted runtime to access the Befu HD tool.
4. Uploading the Sketch: Drop the sketch into the designated folder in the Befu HD directory.
5. Configuring Input Data: Copy the path of the uploaded image and paste it into the input data configuration block.
6. Running Befu HD: Execute the Befu HD tool to process the uploaded image and generate the 3D model.
7. Importing the Result into Blender: Import the resulting obj file into Blender for further refinements.
8. Sculpting the Mesh: Use sculpting tools in Blender to refine the Shape and details of the model.
9. Remeshing the Mesh: Apply a remeshing tool to clean up the mesh and optimize the geometry.
10. Refining the Sculpt: Make further adjustments and refinements to achieve the desired final result.

Now that we have a high-level understanding of the process, let's dive into each step in Detail.

1. Preparing the Sketch

The first step in using Befu HD is to prepare the sketch that will be used as the input. The sketch should have a transparent background and a readable human form, although it doesn't need to be photorealistic. The goal is to Create a sketch that can be successfully interpreted by Befu HD. This means ensuring the sketch captures the basic shape and proportions of a clothed human.

2. Copying the Sketch to Drive

Once the sketch is ready, it needs to be uploaded to Google Drive. This can be done by saving the sketch with a transparent background and then copying it to a designated folder in your Google Drive account. This step is necessary to provide Befu HD with the necessary input image.

3. Connecting to Hosted Runtime

To access the Befu HD tool, You need to connect to the hosted runtime. This can be done by logging into your Google account and navigating to the Befu HD page. Once there, you can connect to the hosted runtime by clicking on the corresponding option in the upper right corner of the page.

4. Uploading the Sketch

Once connected to the hosted runtime, you can upload the sketch to the Befu HD tool. This is done by dropping the sketch into the designated folder in the Befu HD directory. By doing this, you provide Befu HD with the input image that will be used to generate the 3D model.

5. Configuring Input Data

After uploading the sketch, it is necessary to configure the input data for Befu HD. This involves copying the path of the uploaded image and pasting it into the input data configuration block. Additionally, any unwanted lines of text can be removed from the configuration block to ensure smooth processing.

6. Running Befu HD

With the input data configured, it's time to run Befu HD and let it process the uploaded image. This can be done by expanding the runtime options in the header and selecting the "run" option. Befu HD will then begin processing the image and generating the 3D model.

7. Importing the Result into Blender

Once Befu HD has finished processing the image, the resulting obj file can be imported into Blender. Blender is a powerful 3D modeling software that allows for further refinements and adjustments to the 3D model generated by Befu HD. Importing the result into Blender opens up a wide range of possibilities for creating detailed and realistic characters.

8. Sculpting the Mesh

With the 3D model imported into Blender, it's time to start sculpting the mesh. Sculpting is a process that involves manipulating the shape and form of the 3D model to add details and refine its appearance. This can be done using various sculpting tools in Blender, such as the grab brush, Clay strips, and scrape brush. The goal is to achieve a level of detail and realism that is suitable for the intended purpose of the 3D model.

9. Remeshing the Mesh

Once the sculpting process is complete, it's important to remesh the mesh to optimize its geometry. Remeshing involves cleaning up any messy geometry and ensuring that the mesh is manifold. This can be done using Blender's built-in remeshing tools, such as the quad remesh or quadriflow remesh. By remeshing the mesh, you can achieve a cleaner and more efficient geometry that is easier to work with.

10. Refining the Sculpt

After remeshing the mesh, it's time to refine the sculpt further. This involves making any additional adjustments and refinements to the shape and details of the model. It's important to iterate and fine-tune the sculpt until you are satisfied with the final result. This step allows you to add those finishing touches that bring the 3D model to life.

11. Conclusion and Future Tutorials

In conclusion, Befu HD is a powerful tool that allows artists and creators to transform sketches into 3D models with impressive detail and accuracy. While the initial results may not always be perfect, Befu HD provides a solid foundation that can be further refined and sculpted to achieve the desired final result. In future tutorials, we will explore additional techniques and workflows to take your 3D models to the next level, including animated sequences and texturing. Stay tuned for more exciting tutorials!
