Blender - Auto Unwrap v1.1.0

One-click UV unwrapping tool - organic models, hard-surface parts and even garments. Select, press Unwrap, done.

The engine reads your model, decides where to cut, and lays every piece flat with minimal stretching (built on the OptCuts engine).

Before unwrapping, the model is automatically split into parts: see them in color with Show Parts, pick and merge the ones that belong together, and only then unwrap - up to 5,000 parts.
