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. 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!

Pack thousands of UV islands in seconds on the CPU. Pack even faster with Cuda GPU acceleration!

Efficient processing of a huge number of UV islands.

Use the CPU and all GPUs simultaneously to perform the operation.

Ultimate tool for advanced UDIM scenarios: split UV islands into any number of named groups
Pack all groups with a single click with full control over:
target UV boxes for each group • relative texel density • group packing order (groups may be packed on the top of each other)

Prioritize UV islands during packing: assign a scale limit to islands with less priority

Scale of the selected islands limited to 100% before packing.

Islands with limited scale were not scaled up during packing.

Not only for UV packing – UVPackmaster is now also an advanced UV aligning tool!
Stack UV islands with:

vertex position correction • automatic scale adjustment • different priority for each island

Many similar islands with slightly different vertex positions.

Islands stacked by UVPackmaster with perfect vertex matching.

Run a heuristic search to find the maximally-dense packing
Iterate on the CPU and all GPUs in the system simultaneously to find the best possible packing in a second! and much more.
