Moar progress, even if I'm a bit slow lately because of ongoing projects :
Implemented the thing as a plugin

New commands to add often used shaders


More shaders available for insertion in existing node tree, some with unique behaviors



Added something for the tidy maniacs

Finally solved something that was bothering me from a long time
Create mask directly from the active selection and (almost) never bother again with ID numbers

It works on objects and materials, and can create one mask for each selected element or a shared one


For sure it's not really useful if you can leverage Cryptomatte but otherwise, it makes the process a bit simpler and faster.
