How to Change Image Texture in Paint 3D

Whether it's game design, animation, or architectural visualization, the selection and adjustment of textures play a crucial role in enhancing the final result. As a professional 3D designer, I often rely on simple, user-friendly software for texture editing and optimization, and Paint 3D is one of my go-to tools. While it may not offer the extensive features of advanced 3D modeling software like Maya or Blender, Paint 3D is a highly convenient and intuitive tool, especially for basic image texture modifications. In this article, I’ll walk you through how to change image textures in Paint 3D, helping you streamline your workflow and achieve better results.

1. Importing Images and Preparing Your Work
The first step in changing textures in Paint 3D is importing the image or model you want to modify. This is the foundation for any texture adjustments you’ll make.
Importing Images: You can easily drag any image file (such as JPG or PNG) into the Paint 3D interface. Once imported, you can view the entire image and make further edits as needed.
Importing 3D Models: If you want to change the texture on a 3D model, you’ll first need to import the model into Paint 3D. Supported file formats include STL, OBJ, and 3MF. Once the model is imported, you can begin adjusting its surface textures.
2. Choosing the Right Tools for Texture Modification
Paint 3D offers a variety of basic drawing and editing tools that help you modify textures. While it doesn't have the advanced texture tools of high-end 3D software, its simple interface makes it easy to edit textures intuitively.
Brush Tool: The brush tool is great for simple texture modifications. You can choose from various brush types and colors to paint texture details on the surface of the model. For example, you can add patterns, spots, or completely overwrite the original texture.
Sticker Tool: If you need to apply an image texture precisely to the surface of the model, the “Sticker” tool in Paint 3D allows you to paste texture images onto specific areas. You can resize, rotate, and adjust the image to fit the surface of your model perfectly.
3. Adjusting Texture Size and Alignment
After applying the image texture to your model or flat surface, you may need to adjust its size and alignment. Paint 3D provides simple tools for these tasks to ensure the texture covers the area seamlessly.
Resizing the Image: Use the "Resize" function to adjust the texture's size to match the proportions of your model. For models of different sizes, it's important to ensure the texture remains clear and at an appropriate resolution to avoid blurriness.
Rotating and Flipping: Sometimes, textures need to align with the direction of the model's surface. The rotate and flip functions allow you to adjust the texture so it aligns properly on different parts of the model.
4. Enhancing Texture Appearance with Material Effects
In Paint 3D, you can use material effects to make textures appear more realistic and three-dimensional. While the material editing options are limited compared to professional tools, basic adjustments can still significantly improve the texture’s visual impact.
Glossiness Adjustment: For metallic or glass-like textures, you can adjust the glossiness to make the surface appear more reflective. By choosing different material types, you can give your model a variety of visual effects.
Texture Blending: If you’re using multiple textures or layers, you can experiment with blending options to ensure they connect seamlessly. This helps to avoid noticeable seams or abrupt transitions, creating a more natural texture effect.

5. Fine-tuning with 3D Perspective
When adjusting textures on 3D models, having the correct perspective is crucial. Paint 3D offers multiple viewing angles and rotation tools to help you see every detail and make precise adjustments.
360-Degree View: You can freely rotate the model to view the texture from different angles. This is especially useful for checking if there are any texture overlaps, distortions, or stretching.
Focus Control: If a specific part of the texture requires close attention, you can use the focus control feature to zoom in on that area, allowing for finer adjustments.
6. Previewing and Exporting the Final Result
Once you’ve made your texture adjustments, the final step is to preview and confirm the texture's application. Paint 3D offers a live preview feature, allowing you to see the texture changes as you make them.
Live Preview: You can view the texture’s appearance in real time as you edit. This helps you check how it looks under different lighting conditions and ensure it meets your expectations.
Exporting the Result: When you’re satisfied with your texture modifications, you can export the file in your desired format. Supported file types include PNG, JPEG, and even 3D model formats, making it easy to use the textures in your future work or rendering processes.
By following these steps, you can efficiently change image textures in Paint 3D, improving both your workflow and the quality of your projects. Whether you're making simple texture adjustments or refining textures on complex 3D models, Paint 3D offers an intuitive and straightforward solution.
