Blender's texture painting feature allows artists and designers to add colour, texture, and intricate details to their 3D models. To add paint to an object in Blender, you must first prepare your model for painting by assigning a material to it. Next, add a texture slot by selecting the desired material in the Object Data Properties panel and clicking Add. Choose the type of texture you want, such as a diffuse or bump texture. Then, unwrap the model by pressing U on your keyboard to initiate a UV unwrap, which maps the textures onto the 3D model. After that, you can prepare your brushes by adjusting their size, strength, and other properties in the Tool tab of Blender's Properties panel. Finally, you can begin painting directly onto your model.

What You'll Learn
Prepare your model for painting
To prepare your model for painting in Blender, there are a few key steps to follow. Firstly, ensure that your model has a material assigned to it. If it doesn't, you'll need to create a new material and assign it to your model. This is an important step, as it provides a base for the painting process.
Next, you'll want to add a texture slot. Go to the Object Data Properties panel, select your assigned material, scroll down to the "Textures" section, and click on "Add." Here, you can choose the type of texture you want to create, such as a diffuse or bump texture. This step allows you to define the characteristics of your model's surface.
Now, it's time to unwrap the model. Texture painting requires a UV unwrap to properly map the textures onto the 3D model. If your model hasn't been unwrapped yet, simply select it and press "U" on your keyboard. You'll then choose the appropriate unwrapping method from the menu. This step ensures that your textures are applied accurately to the model.
Before you start painting, it's a good idea to prepare your brushes. Go to Blender's Properties panel and locate the "Tool" tab. Here, you can customize your brushes by adjusting their size, strength, and other properties to suit your desired effect. This step ensures that you have the right tools set up for the painting process.
Additionally, you can use texture stencils and masks to enhance your painting process. Texture stencils allow you to project predetermined textures or images onto your 3D model, adding intricate details and designs. On the other hand, texture masks let you control the specific areas where the paint is applied. You can use black and white images or procedural textures as masks to limit the painting effects to certain parts of the model, creating complex and realistic textures.

Add a texture slot
To add paint to an object in Blender, you will first need to set up a material with a blank texture and assign it to your object. This is how Blender knows that this texture belongs to your object. Once you have that set up, you can start painting.
To add a texture slot, click on the Tools tab on the right. At the top of your main window in the middle, there is a little drop-down menu (if you have your top bar flipped to the bottom, it will be in the middle at the bottom). Click the drop-down, and you will find the mode, all your materials listed, and a + to add the texture slot. Then you can just select brush, colour, and paint without needing to use nodes.
If you are using Blender 4, the texture slot under the workspace has moved to the active tool settings. You can create a new image or material, such as a new material with a base.
In the UV Image Editor, press New Image to create your texture. Don't forget to save your texture with F3 and save it as an image.

Unwrap the model
To unwrap a model in Blender, you must first UV unwrap it. This process involves "unwrapping" the object mesh on a plain surface, allowing you to paste textures onto the object accurately. Here is a step-by-step guide on how to unwrap a model:
- Ensure you are in the correct layer and mode: You must be in edit mode on a mesh, not an armature, to do UV unwrapping. Select the model by clicking on it in object mode, then press Tab to enter edit mode.
- Add a material to the object: Click on "Material Properties," then click on the + icon to add a material slot. Click "New" and rename the material to something recognizable.
- Plan the seam placement: Before unwrapping, figure out the flow of the mesh and plan where to place the seams. Blender will "cut" the 3D model and try to flatten it along these seams, so ensure it can split into even planes to avoid warping issues.
- Mark the seams: Open a UV editor and start placing the seams on the mesh. Use the shortcut Ctrl+E, then Mark Seam.
- UV unwrap the model: Use the shortcut U, then Unwrap to unwrap the model. Ensure it unwrapped as expected, and tweak the seams as needed until you are happy with the result.
- Scale and position the UVs: In the UV Editor, scale down the unwrapped UVs and line them up neatly. Make sure none of the UVs overlap with one another.
- Paint and add textures: Choose your preferred paint software and import the UV layout image. Add colours and textures to the UVs. Remember not to export the image with the UV layout displayed.
With these steps, you can unwrap your model in Blender and prepare it for texture painting.

Prepare your brushes
To prepare your brushes in Blender, you will need to access the "Tool" tab in Blender's Properties panel. Here, you can customise your brushes by adjusting their size, strength, and other properties to achieve the desired effect.
Blender offers a variety of brush options to choose from. You can adjust the brush size to suit the area you are painting. A larger brush size will cover more surface area, while a smaller brush size will allow for more detailed and precise painting. The strength of the brush, or the opacity, can also be adjusted to control the intensity of the colour or texture being applied. A stronger brush will result in a more opaque application, while a weaker brush will produce a more subtle, translucent effect.
Additionally, Blender allows you to create custom brushes. You can experiment with different brush shapes, textures, and settings to achieve unique effects. For instance, you can use texture masks to control the areas where the paint is applied. Black and white images or procedural textures can be used as masks to limit the painting effects to specific parts of the model, allowing for complex and realistic textures.
If you are familiar with Maya, you can replicate its 3D paint tool features in Blender. In Maya, you can use the "3D paint tool" in the render menu to add colour and texture to your objects in real time, without the need to render each time you move your object. To achieve similar results in Blender, you can utilise texture stencils, which allow you to project predetermined textures or images onto your 3D model. By importing or creating custom stencils, you can add intricate details, designs, and real-world textures to your artwork.
Blender's texture painting feature provides artists and designers with a versatile tool to add colour, texture, and intricate details to their 3D models. With custom brushes and texture stencils, the possibilities for creative expression are endless.

Use texture stencils
Texture stencils in Blender enable you to project predetermined textures or images onto your 3D model. You can either import or create custom stencils to add intricate details or designs to your artwork. This technique is particularly useful for replicating real-world textures or intricate patterns such as engravings on armour or scales on a dragon.
Blender also provides the option to paint directly on the UV map of your model. This method allows for precise control over texture placement and avoids distortion or stretching that may occur during the unwrapping process. It is especially useful for precise texturing, such as labelling or branding on objects.
To use texture stencils in Blender, you need to follow these steps:
- Prepare your model for painting: Ensure that your model has a material assigned to it. If not, create a new material and assign it to your model.
- Add a texture slot: Go to the Object Data Properties panel, select the material assigned to your model, scroll down to the "Textures" section, and click "Add." Here, you can choose the type of texture you want to create, such as a diffuse or bump texture.
- Unwrap the model: Texture painting requires a UV unwrap to map the textures onto the 3D model correctly. If your model is not unwrapped, select it and press "U" on your keyboard to choose an unwrapping method.
- Create or import a texture stencil: You can either create your own custom texture stencil or import an existing one. When creating a stencil, you can use black and white images or procedural textures as masks to limit the painting effects to specific parts of the model.
- Project the texture stencil onto your model: Once you have your texture stencil ready, you can project it onto your 3D model. This will enable you to see how the texture or design will look on your model before finalising it.
- Adjust and refine: Make any necessary adjustments to ensure the texture aligns with your desired outcome. You can adjust the placement, size, and other properties of the texture to achieve the desired effect.
By following these steps, you can utilise texture stencils in Blender to add intricate details and designs to your 3D models, enhancing the visual appeal and complexity of your artwork.
