Blender Texture Painting Not Working: A Comprehensive Guide to Troubleshooting


Written by Hayden

Published on Last Updated on


Texture painting in Blender is a powerful tool that allows artists to paint directly onto 3D models, bringing them to life with color and detail. However, like any software, Blender can sometimes encounter issues that prevent texture painting from working as intended. In this guide, we will explore common problems that users may face when texture painting in Blender and provide step-by-step troubleshooting solutions to help you get back on track.

Understanding Texture Painting in Blender

Texture painting in Blender involves applying a 2D image, known as a texture, onto a 3D model's surface. This process allows artists to add color, patterns, and details to their models, creating realistic and visually appealing renders.

Troubleshooting Common Texture Painting Issues

Now that we have a basic understanding of texture painting in Blender, let's explore some common issues that users may encounter and provide step-by-step troubleshooting solutions:

Issue 1: Texture painting mode is not active

If you're unable to paint on your model, the first thing to check is whether the texture painting mode is active. Follow these steps:

  1. Enter Texture Paint mode: In the 3D viewport, select your model and navigate to the Properties panel, located on the right side of the screen. In the "Materials" section, click on the "Texture Paint" button to activate the texture painting mode.
  2. Check the active texture: By default, Blender will access the first image texture in the material that it finds. If your object is pink it means that there is no texture currently available.
  1. Create a new texture via the texture slots in the properties - or via the material editor (then making sure to select it in the texture slot)

You should now be able to use texture painting.

Issue 2: Brush strokes are not appearing

If you can't see the brush strokes on your model, follow these troubleshooting steps:

  1. Check the brush settings: Make sure that the brush size, opacity, and hardness values are set to a visible range. If these values are too low, the brush strokes may be very faint or invisible.
  2. Inspect the brush stroke method. Your method settings may have been changed. For example in the case of space - you want to ensure that the spacing between the samples are not too far (in most cases) otherwise it might appear that your brush is not doing anything. When in fact it is just waiting till enough space is available to place the next sample.
  1. Ensure that the tool that you have selected is the paint tool and not another tool, such as smear.

Issue 3: Painting is not visible after rendering

If your painted texture is not visible in the final render, consider the following solutions:

  1. Check the material setup: Ensure that the material assigned to your model is set up to use the painted texture. In the "Shader editor," make sure that the "Image Texture" node is connected to the appropriate shader node. Additionally, confirm that the node's "Color" output is connected to the "Base Color" input of the shader node.
  2. Verify the rendering engine: Some rendering engines, such as Blender's Cycles, require specific material configurations to display texture painting results. If you're using Cycles, make sure that the "Viewport Shading" is set to "Rendered" mode and that the necessary nodes are correctly configured.

Issue 4: Painted texture appears distorted or stretched

If your texture appears distorted or stretched on the model's surface, you may need to adjust the UV mapping. Follow these steps:

  1. Enter Edit mode: Select your model and switch to Edit mode. You can do this by pressing the "Tab" key or selecting "Edit" from the Mode dropdown menu located at the top of the 3D viewport.
  2. Inspect the UV layout: With the model in Edit mode, make sure that the UV islands are not overlapping, stretched, or distorted. Use the UV editor to adjust and arrange the UV islands, so each island corresponds accurately to the model's surface.
  3. Revisit the texture painting: After rearranging the UV islands, return to Texture Paint mode and verify if the painted texture appears correctly on the model. If not, go back to Edit mode and make further adjustments until the desired result is achieved.

It should be noted that you should only change the UV’s if you are 100% sure that they are the culprit and that you only require small changes.

If you will need to redo the UV’s you will need to rebake the texture - And if that texture has a problem such as distortions or stretches - they will carry over.

That is why it is very important to test your UV’s with either a color grid or a uv grid.

Issue 5: Everything is one color and not updating

If your texture appears to be one solid color that is not pink, remembering that pink is a sign that there is no texture. (usually black) Usually what is happening is the UV has been reset, zeroed or not created.

It will look something like this. There will be a little orange(or black if not selected) dot that represent your UV’s… I like to called this a UV Black Hole.

  1. Navigate to your UV editing workspace
  2. Select your model and enter edit mode. Then select everything by pressing the “a” key. Or choosing select -> select all.
  3. You should see your UV map in the left window. If you do not, check all the corners of the image bounds. If you see a single point that is highlighted orange. It means that all the UV’s are converging on a single point - which is why it is only showing one color!
  4. Recalculate your UV by pressing “U” then unwrap - There are a number of different ways to unwrap your UV - but this is the most basic.


Texture painting in Blender can add depth and realism to your 3D models, but it's not immune to issues that may hinder its functionality.

 By following the troubleshooting steps outlined in this guide, you can address common problems and ensure that texture painting works as intended. Remember to check the texture painting mode, brush settings, material setup, and UV mapping to pinpoint the root cause of the issue. 

With patience and practice, you will be able to unleash your creativity and produce stunning texture-painted renders in Blender.

If after all of this you are still struggling with this - it may be prudent to get professional help. Consider contacting a consultant or teacher.

About the Author


Hello there, Blendertutorials story begins with an idea. An idea to make learning 3D more accessible and easy. There are a lot of great tutorials out there, but very few that truly have the scope or the functions of blender tutorials. My aim with this site was to create something unique, that may help people achieve their dreams with 3D. Despite the name blender tutorials and myself using the software for near on 15 years, I don't like to consider myself a Blender Artist, rather I am a story teller first and foremost. I believe Blender is a tool and it should be used in conjunction with other tools. It is for this reason that I teach you from the perceptive of a technical storyteller not a Blender Artist. And I feel that that is a defining feature of Blender Tutorials. Yes, we look at the technical side of 3D art through the lens of Blender. But it is all in service of telling a story. It has been such a journey to try and create this service. When I started. I had only limited knowledge of creating websites. Now... well... I am quite happy with the outcome. I have learnt so much on this journey from myself and from all of you that join me on it. Thank you so much for making blender tutorials apart of your learning!
