GPU-accelerated, scriptable UV packing engine
UVPackmaster 3 is an efficient and fully-featured UV packing engine for Blender. It is the most efficient UV packer out there in terms of packing on CPU, but it also provides a Cuda accelerated variant of the algorithm (on Windows and Linux). When running on a GPU, it significantly outperforms all other packers available.

Not only a UV packing tool!
UVPackmaster is not only a state-of-the-art UV packing solution – it also introduces an advanced UV aligning/stacking algorithm and other auxiliary tools, greatly simplifying your UV workflow. All these functionalities run with engine-acceleration for maximum efficiency.

The scriptable architecture for maximum flexibility!
UVPackmaster is not a black box anymore. We embedded Python into the newest engine release, giving you a possibility to code your own operation logic, perfectly adjusted to your own most demanding workflows!
