Troubleshooting

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.

I activated the add-on but I cannot find the UVPackmaster interface in Blender

Keep in mind that the add-on UI is present in the N panel of the UV editor in Blender (not in the 3D Viewport).

The UVPackmaster add-on initializes correctly, but packing functionalities are not working (the UVPackmaster engine is not initialized)

First of all make sure you correctly followed the installation guide for UVPackmaster in Blender.

If you followed the guide and the issue still persists, check your antivirus software configurations - it may be the case that it is blocking the packer binary from being run. (Some antivirus software is picky about an executable being called from a Python script, such as in the case of UVPackmaster – it is a false positive alert). If you are on Windows, make sure you have Visual Studio Redistributable 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 computing capability 3.0 and higher and Vulkan-enabled GPUs supporting Vulkan 1.2. If you have such a card and still don’t see it in the packing device list, then installation of the latest GPU driver should solve the problem.

I am receiving a “Inconsistent islands found” error
