Blender UV Unwrap & Texture Paint for Each Island – Smart UV vs Manual Seam

In this beginner-friendly Blender tutorial, you’ll learn how to unwrap your 3D model and assign different materials or paint colors to each UV island. We’ll start with the Smart UV Project method, then explore a more precise and clean approach using manual Mark Seam + Unwrap (Minimum Stretch). You’ll also learn how to: • Use UV Sync Selection to link 3D selection with UV islands • Quickly select islands with the L key • Assign separate materials to each island • Set up Image Texture nodes for painting • Paint directly on the mesh using Texture Paint mode
