Material Creator Plugin Demo

This plugin demo contains a custom material creator interface using a custom dock in the editor.

Custom docks are made of Control nodes, they run in the editor, and any behavior must be done through tool scripts. For more information, see this documentation article: https://docs.godotengine.org/en/latest/tutorials/plugins/editor/making_plugins.html#a-custom-dock

This plugin allows you to specify color, metallic, and roughness values, and then use it as a material.

You can apply this material directly to Spatial nodes by selecting them and then clicking "Apply". This shows how a plugin can interact closely with the editor, manipulating nodes the user selects.

Alternatively, you can also save the material to a file, and then load it back into the plugin later.
