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 do not work

If packing functionalities do not work (the engine is not initialized or the add-on reports unexpected errors): 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 the following list:

• 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.

• Update GPU drivers to the latest version.

• Sometimes the engine cannot run due to incorrect configuration of Vulkan drivers. You can disable Vulkan acceleration and check whether it solves the problem:

  • go to the Add-on Preferences multi panel:

    

  • uncheck the Enable Vulkan option,

  • press the Save Preferences button at the very end of the multi panel,

  • restart the application.

If the issues persist, contact us directly at support@uvpackmaster.com.

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
