Today, I added sprinkles to my donut. This sounds like it would be a relatively simple procure, but the process to get there included quite a number of steps. This involved using geometry nodes, similar to the nodes used for textures, but designed for altering geometry and 3D forms instead. Using a scatter feature, I was able to create a simple sphere and “scatter” it along the surface of the icing. I was able to alter the size of the sprinkles, the amount of them, and the distance they sit apart from each other for as little clipping as possible. While this sounds all well and good, the sprinkles were scattered along every surface of the icing rather than just the top. This included the “drippy” parts and the underside of the icing as well.
Using a feature called weight paint, I was able to paint on my icing where I wanted the sprinkles to appear. I was then able to further limit the amount on the donut. Following this, I scaled the donut down in size as it was currently about 1.5m long. That is far too large for a donut, and while the size wouldn’t seem to matter when making just a single donut, it is good practice to keep things at an easy-to-reference uniform scale when 3D modelling for when other materials and forms are added to a scene.
While this is a shorter update, there is more to come as next time I learn how to put cylindrical sprinkles on my donut! Below I have attached a picture of my process and Blender Guru’s tutorial that I followed for this step of my Blender journey.
