Here is my attempt at following the very popular tutorial for making a doughnut in the Blender 3d Modelling software. The tutorial is spread over 24 video tutorials and took me roughly 40 hours to make the one you see below.
The video-series explains in detail; working with shapes, vertices, meshes, sculpting, texturizing your doughnut, creating the correct lighting for your scene and finally rendering.
