UnwrellaConnect: Free Blender Extension
UnwrellaConnect: Free Automatic UV Unwrapping and Packing Extension for Blender
June 2025 – The makers of Unwrella-IO and Packer-IO are proud to announce the release of UnwrellaConnect, a free Blender extension that brings fully automatic UV unwrapping and UV packing directly into Blender’s native workflow.
Built on the acclaimed Unwrella-IO and Packer-IO engines, UnwrellaConnect eliminates one of the most tedious steps in 3D production — manually creating UV seams and layouts. With a single click, artists can generate optimal UV seams, unfold geometry, and pack thousands of UV islands with minimal space waste.
Designed for speed and flexibility, UnwrellaConnect offers three intelligent unwrapping modes:
- Hard Surface – for clean, instant UVs on mechanical and low-curvature forms
- Organic – for smooth, quad-based models like characters and creatures
- Mosaic – for messy topologies, photogrammetry scans, and complex triangulations
UnwrellaConnect also includes QuickPack, tile UV support, and texel density management, all wrapped in a clean and intuitive interface.
Artists can use UnwrellaConnect freely with Packer-IO for high-efficiency UV packing, or pair it with Unwrella-IO for a full automatic UV solution.
UnwrellaConnect is available now — free to download.
