This 100% node-based procedural donut was built using Blender’s Geometry Nodes and Shader Nodes, no external textures, no baked meshes, just pure Blender. Designed for Blender 4.5+, it features a deeply customizable modifier panel, letting you fine-tune everything from shape and shading to frosting style and sprinkle chaos.

Features:

🍩 Donut Customization

Adjust size, thickness, and surface lumpiness Dynamic “uncooked band” for that half-baked realism Subdivision and torus resolution controls for optimized topology

🍫 Frosting Controls

Full control over color, roughness, thickness, and coverage Adjustable lumpiness for a drippy or smooth finish Uses Blender 4.5’s new Boolean tools for clean, efficient frosting cuts

✨ Sprinkle Generator

Set sprinkle spacing, density, and cutoff height Choose between cylindrical or spherical shapes Toggle rainbow mode with fully adjustable bright/dark RGB ranges and seed for randomness Fine-grained control over individual sprinkle size, resolution, and animation-ready offset

🎨 Shader Integration

All materials are procedurally driven; color, roughness, bump, and even subsurface scattering react to the donut's geometry in real-time Uncooked band drives shader variation for more realistic baked edges and glossy inner ring Sprinkles and frosting inherit shading dynamically from geometry node attributes
