Blender Texture Painting: Paint Textures Directly on Your Mesh

A brush, a mesh and a blank image: Blender's Texture Paint mode lets you paint textures directly on the model without leaving the viewport. There is no need to export anything or open another program: the mesh becomes a canvas and every stroke is recorded in the UV image.

What is Texture Paint and when to use it?

Texture Paint is Blender's integrated painting mode, designed to edit UV textures and images quickly, both in the Image Editor and in the 3D Viewport itself. It is the natural path for stylized assets, props and quick touch-ups: painting a rust stain, fixing a seam or giving an object a hand-painted character.

When should you not use it? If what you need is to transfer dense PBR detail from a high-resolution mesh, map baking is the right tool. Texture painting shines at manual control: you decide every stroke.

Setting up the canvas: image and material

Creating the image

Before painting you need an image. New Image creates a canvas with the resolution that fits the use; a game texture does not need 8K. A practical tip: leave a margin of about 16 px when creating it so that strokes reach the seams between UV islands and no borders are left unpainted.

Connecting the image to the material

An image alone does nothing visible: it has to be connected to the material. Add an Image Texture node to the Base Color of the Principled BSDF and select the image you just created. From that point on, what you paint shows up in the render.

Texture slots

Texture slots are the combination of images associated with the object's UV maps. Material mode automatically detects the slots from the mesh materials, while Image mode lets you work with a specific image. The active slot is the one shown in the Image Editor, and it is where the strokes are applied.

The brushes: Draw, Soften, Smear, Clone, Fill and Mask

Painting brushes

The mode ships six basic tools. Draw paints the active color; Soften smooths existing detail; Smear drags the paint as if you were spreading it with a finger; Clone copies from another area of the image or from another image; and Fill floods a region with color. With that set you cover most hand-painted workflows.

The Mask brush

Mask is the special brush: it paints grayscale values on the mask texture. Masked surfaces are not affected by the other brushes, just like masking in Sculpt Mode. It is the fast way to protect areas: you paint the mask, work on the rest with peace of mind and clear it when you want.

Brush settings that change the result

Core parameters

In the Tool Settings you have the controls that define every stroke: Radius (size), Strength (force), Blend Mode (Mix, Multiply, Erase Alpha, among others), Falloff (stroke falloff toward the edges) and Spacing (distance between stamps). Mastering the combination of these parameters changes the result more than the brush itself.

View-angle dependence

The Normal option makes the brush react to the angle of the face relative to the view: surfaces that are almost perpendicular receive little paint and front-facing ones receive a lot. It is subtle, but it gives a more natural result when painting curved shapes.

Brush textures

You can also use a texture as the brush tip. That is the way to get repeatable detail: a grain, rust or rubber texture gets stamped along the stroke with the scale and spacing you configure.

Stencils: painting with precision

Stencils turn an image into a template: you use it as a visual mask to paint details with defined limits. With the Occlude option active, you can also use 3D stencils that conform to the model's surface, masking the areas of the geometry you do not want to touch. It is the most direct way to paint an emblem or a pattern without going over the edges.

Options: Bleed, Dither and Occlude

Bleed

Seam Bleed extends the paint beyond the limits of the UV island. It is the same concept as baking bleed: it prevents visual artifacts at the seams when the model is compressed or filtered. With it active, the joins between islands stay clean.

Dither

Dither controls the amount of dithering when painting on 8-bit images. If you see banding or color jumps in smooth gradients, raising it helps blend the transitions.

Occlude and backface culling

With Occlude active, only exposed pixels are affected: parts of the mesh hidden by other geometry are not painted even if the stroke passes in front. Backface Culling, on the other hand, avoids painting back faces, which is useful when working with thin meshes.

Saving your work: the image does not save itself

This is the classic beginner mistake: the painted image is a data-block in memory. If you close Blender or switch projects without saving it, the work is lost even if you saved the .blend file. The image is saved with Image > Save (or Save As) inside the Image Editor. Before closing, check the modified indicator that warns about unsaved changes.

Conclusion

Painting by hand in Blender is fast when the goal is a stylized asset or a touch-up: you prepare the image, pick a brush, protect what you do not want to touch and remember to save the image at the end. Combined with clean UVs and baking for PBR detail, texture painting completes the whole texturing workflow without leaving Blender.
