UVPackmaster 2 is an efficient and fully-featured UV packing engine available also as a plugin for 3ds Max. Its robustness comes from the fact that it was written in C++ and can perform packing on CPU, as well as on Cuda-enabled GPUs.
The plugin for 3ds Max provides all core features of UVPackmaster engine PRO edition:
efficient UV packing algorithm
UV islands area measurement
overlapping UV islands detection
heuristic search algorithm
packing for a non-square texture
add new UV islands into an existing packing
accurate pixel margin calculation
overlapping UV islands lock
grouping UV islands
UDIM support
advanced heuristic algorithm
packing on GPU
heuristic search on all devices simultaneously (CPU and all GPUs)
