This one-hour video tutorial covers a workflow for cleaning and UV unwrapping a 3D model of a hydrant in Blender. The instructor demonstrates techniques for preparing a mesh with uniform edge flow and creating clean UV maps suitable for texturing in applications like Substance Painter, Blender, or Mari. The process includes checking the mesh for necessary edge loops, adding seams, unwrapping, and refining problematic UV islands. Finally, the tutorial covers exporting low and high-resolution models to Substance Painter for baking maps such as Ambient Occlusion and Normals. The workflow utilizes Blender add-ons like RMB Pie Menu and Textools.
