ShapeItUp adds more than 25 shapes and patterns to your Shader Editor when creating procedural material.

You have three main node groups:

Main_Shape, which gives you about the same shapes as you have in the tool "Substance Designer" when you select the node "Shape" there.

Main_Pattern, which give you good to have patterns like polygons, flowers, fibers, weave and similar.

Main_Mask, which give you the ability to very easy mask away parts of your image, either by using an input mask or simple filter in the X and Y direction.

In the two nodes for shapes and pattern, you can tweak almost every shape and also change things like scale, rotation, random color, tiling amount and random leaning. You will recognize it if you have been working with "Substance Designer" since I use about the same parameters.

I have also added a few example materials to get you going.

Everything is fully visible and you can add your own functionality to it or change what I have already built for you. It's only imagination and skill that stops you.
