I see an error when trying to activate the Blender add-on
Restart Blender once - it should fix the problem. Blender restart might be also needed after upgrading to a newer add-on version.
The UVPackmaster add-on initializes properly, but packing functionalities are not working (the UVP engine is not initialized)
If you have antivirus software installed, check whether it is not blocking the packer binary from being run. (Some antivirus software is picky about an executable being called from a Python script, as it is the case with UVPackmaster - it is a false positive alert). If you are on Windows, make sure you have Visual Studio Redistributable 2017 from Microsoft installed - it is required for the engine to run.
I don’t see my GPU in the packing device list
Note the packer supports CUDA-enabled GPUs with compute capability 3.0 and higher. If you have such card and still don’t see it in the packing device list, then installation of the latest GPU driver should solve the problem.
