Adds many premade 2D effects (such as noises, blur, emboss, zoom, custom shapes, etc.) to build-in VisualShader editor.

You can find basic usage examples in the addons/shaderV/examples folder. Note that plugin can work freely without examples folder, so this folder can be deleted.

Copy the contents of addons/shaderV into the same folder in your project. No activation needed. Custom visual shader nodes work the same way as standart visual shader nodes.
