Vulkan GPU Acceleration

Starting from version 3.3.0, UVPackmaster supports packing on GPU using also the Vulkan API (alongside with Cuda). Note that Cuda is still the default API to use on all NVidia GPUs - UVPackmaster doesn’t list NVidia GPUs as supporting Vulkan. Vulkan can be used to accelerate packing on AMD Radeon and Apple M Silicon GPUs.

Contrary to Cuda, Vulkan devices are disabled by default. In order to enable a device:

  1. Go to the Add-on Preferences multi panel:

  2. Check the Enabled check box next to a Vulkan device name:

  3. Press the Save Blender Preferences button to make the change permanent.

Current limitations

  • Vulkan devices doesn’t currently support the Groups Together packing mode but keep in mind UVPackmaster will automatically switch to a packing device which supports the mode when needed (e.g. the CPU device).
