Master the Art of Creating Consistent Faces for Ai Influencers: A Step-by-Step Fooocus Tutorial
Welcome, everyone! Have you ever thought about creating your own virtual model or AI influencer? Well, now you can! With an amazing tool called Focus, you can create any face you like and generate consistent images of that same person. It's a fascinating process that we'll explore in this step-by-step tutorial. Whether you're a technical expert or just an avid learner, we've got you covered. So, let's dive in and master the art of creating consistent faces for AI influencers!
Installing Focus and Navigating the Interface
Before we get started, let's install Focus and become familiar with its user interface. The installation process is incredibly simple, and I'll guide you through it. Just follow along!
Now, according to the official documentation, you'll need a minimum of 8 GB of system RAM and an Nvidia GPU with 4 GB of video RAM. Additionally, make sure you have around 33 GB of disk space and Pinocchio installed. If you need assistance with Pinocchio installation, check out this helpful video.
Once you have Pinocchio open, the only challenging part is locating Focus in the discovered tab. But don't worry, once you find it, all you need to do is click "download" twice and then install. After downloading some large model files, your web browser should open, allowing you to start using the tool right away!
Let's take a quick tour of the user interface. While some parts may be obvious if you've used stable Fusion before, I'll explain everything in case you're new to it. To make things even easier, I'll walk you through the basics of Focus's UI.
The main interface of Focus is quite simple, but if you want to unlock advanced options, you can enable them down here. This will give you access to some performance presets that we'll explore later in more detail.
Here, you can adjust the resolution and the number of images you'd like to generate. Additionally, this is where you can enter the negative prompt. If you untick this box, you'll be able to manipulate the seed in the style tab.
In the style tab, you'll find a wide range of styles that you can easily apply to your image. We'll delve deeper into this feature later on. In the model tab, you'll see that "Jugger out XL" is selected by default, as it's been automatically downloaded during the installation. You can choose another checkpoint or select "refiner," but remember that Focus only supports sdxl checkpoints.
Now, let's talk about the advanced tab. In this tab, you'll find the settings for the guidance scale, which determines the strength of your prompt, and the image sharpness, which influences the softness or hardness of the image's edges and textures. We'll discuss these in more detail as we proceed.
Creating a Base Image and Fixing Imperfections
Alright, it's time to start creating our base image, which will serve as the foundation for all the other images we'll generate. For the prompt, I visited Civit AI and copied and pasted the prompt from the checkpoint we're using. I made a few modifications and anxiously hit enter to see what results it would yield.
Now, here's a cool tip: you can use multiple images as input in Focus, just like with control net. This allows you to combine certain features from different images. In this particular example, we want to use our model's face again, so we set the setting to "Face Swap." For a bodybuilding pose, we use "pyro Kenny," which works wonders for poses. And for the background, we use an image with the "cpds" preset, as it works great with any structure. The result is a fantastic blend of all our chosen images!
But what if you have an image you like, yet it's not quite perfect? Don't worry, Focus has got you covered. In the "inpaint/outpaint" tab, you can easily make the necessary adjustments. Simply drag in the image you want to edit, highlight the area you want to inpaint, and voila! If you want to make additional changes, remember to drag the new image into the inpaint field first, so you don't lose your previous edits.
Wait, there's more! Focus also allows you to expand your image easily. Just set the direction you want to outpaint, and you're good to go! In just a few clicks, you can create a wider image. Even with a simple prompt, you'll be amazed at the level of detail and quality you can achieve!
Exploring Advanced Settings and Generating Variants
Now, let's take a closer look at some of Focus's advanced settings. As we mentioned earlier, the stop at value determines how closely the generated image resembles the input image. By default, it's set to a value that provides a great balance. Experimenting with lower or higher values can yield interesting results, but I recommend sticking close to the default value for optimal output.
Another important setting is the weight. Starting at 0.5, the image starts to resemble the input face. However, the higher you go, the closer it becomes to the input. Increasing the weight value can help if you're not getting the desired resemblance. Just be cautious not to go too high, as it might lose all prompt and become unrecognizable.
Now, let's discuss the performance presets. In my experience, there's hardly any difference between the "speed" and "quality" presets. However, the "extreme speed" preset seems to generate images that look less like the input face. For the best balance between speed and quality, I recommend using the "quality" preset.
Of course, we can't forget about the style presets. With so many options to choose from, the differences may seem subtle at first glance. However, they can have a small impact on the final appearance of the image. Feel free to experiment and find the style that best suits your preferences!
Now, let's talk about the guidance scale. While you shouldn't deviate too much from the default value, you can increase it slightly if you want stronger prompt influence. However, setting it too high or too low can lead to unsatisfactory results, so proceed with caution.
Finally, we have the sharpness setting. At first glance, it may not seem to make much of a difference, unless you select the highest value. However, if you pay close attention to the skin, you'll notice that higher sharpness values result in rougher, more realistic textures. If that's the aesthetic you're aiming for, don't hesitate to increase the sharpness value.
One last tip before we move on - aspect ratio and resolution. Thankfully, Focus provides a range of resolutions that work seamlessly with sdxl. During testing, every resolution from that list produced exceptional results. So, rest assured that no matter which ratio or resolution you choose, you'll achieve remarkable images!
Superior Upscaling and Image Variants
Now, let's say you have an image that you're truly happy with, but you want to upscale it for even greater detail. Don't worry, Focus has you covered again! Simply go to the upscale tab, drag your image into the designated area, select the upscale option, and hit "generate." The result? A beautifully upscaled image that retains all the qualities you love!
Finally, let's touch on the topic of image variants. Although it can be fun to play around with different options, it's important to note that our focus here is on creating consistent faces. Therefore, generating variants might not be as useful for our specific use case. However, feel free to explore this feature and let your creativity run wild!
