How to Make Game Asset Art with AI (Free and Easy) - Stable Diffusion Tutorial 2022

Introduction

Creating stunning game asset illustrations doesn't have to be a daunting task, especially with the help of AI tools like Stable Diffusion. In this tutorial, we'll guide you through the process of turning rough sketches into beautifully illustrated items in the style of popular games like World of Warcraft and Breath of the Wild. You'll learn how to create RPG inventory assets such as a treasure chest, potion bottle, and mace weapon using free software with ease. Let's dive in!

Step 1: Prepare Your Rough Sketches

Start by creating rough sketches of the assets you want to illustrate. You can use digital tools like an iPad or even simple programs like Microsoft Paint on a PC. Your sketches don’t need to be perfect; the goal is to convey the basic shape and idea of each asset. For this tutorial, we’ll be illustrating a chest, a potion, and a mace.

Step 2: Set Up Stable Diffusion

Before you begin, ensure that you have Stable Diffusion installed. You can find updated installation guides in the video description. Using a local installation will enhance performance and allow for greater control. If you do not have access to a powerful PC, cloud-based options are also available.

Step 3: Use Image-to-Image Algorithm

Open the Stable Diffusion interface and use the image-to-image feature to upload your rough sketch. For our first item, the treasure chest, enter a descriptive prompt alongside your sketch for better results. For example, you might write:

A wooden treasure chest with an emerald latch, leather belt, and runes on all sides. Video game art in the style of Shady Safari and Ariel Fain. 8K, intricate, detailed.

Adjusting Settings

1. Sampling Steps: Start with 50 for initial renders.
2. Guidance Scale: Set to around 11 to emphasize the prompt.
3. Denoising Strength: Keep this between 0.3 and 0.4 for closer initial results to the sketch.

Generate your image and evaluate the outputs.

Step 4: Mixing and Refining the Images

Once you've generated some images, you'll likely want to mix elements from the outputs. Paste them into Adobe Photoshop (or a free alternative like GIMP). Utilize masking techniques to remove unwanted parts and keep the best elements from each image.

After creating a composite image, generate another round of images with increased denoising strength to better refine the illustration. Adjust the prompt and details as necessary.

Step 5: Final Touch-Ups

For the final iterations of your artwork, play around with the sampling steps (increase to 150 for more detailed images) and use photobashing techniques for elements like belt buckles or steam. Again, run the selected image through Stable Diffusion for final output, adjusting the prompt as necessary.

Step 6: Upscale Your Image

Once you’re satisfied with your artwork for each asset, you can upscale your images using built-in tools like Real-ESRGAN within Stable Diffusion that will enhance image quality while minimizing artifacts.

Conclusion

With the techniques outlined, you can transform very basic sketches into detailed gaming assets fitting for an RPG inventory system. This method is not only efficient but accessible to everyone, regardless of artistic skill. Enjoy experimenting with AI art tools!
