Single Dose - Glossy stroke 3d.py

[Krikor]

Here there is no message that appears when using the plugin.
When it runs for the first time everything goes well, but there is no second time; or messages of any kind.

I had never clicked on that Filters > Reset all filters option. I hope it only reset the filters I used after restarting Gimp.

As a palliative measure, the solution was excellent. Although it is necessary to reset a few times until a satisfactory fit is found in the plugin configuration, but it is much better than having to restart Gimp every experiment.

Ofnuts, thanks for the solution!

BTW: The Lighting Effects filter in <Image>/Filters/Light and Shadow/ might also benefit from this "Reset all filters" option.
