I made a quick and simple loaf of bread in Blender and colored it in Vertex Paint. Then, I used a Noise Texture and Math Node (Multiply) to create a bread-like effect. This was achieved without the use of an image texture.
Please click on the image above to see a bigger version, so you can take a closer look at the Noise Texture settings!
Thank you for checking out my Blender Note! I am by all means a beginner in Blender, so I do not feel qualified to label this post as a 'tip' or 'tutorial'. However, I decided to upload this note for myself, and hopefully it can be useful to others as well.
