My additionnal functions for shading in Unity, using Amplify Shader plugin.

There is 5 types of functions made :

• Random : some functions for fast randomization with Float and Vec2.
• Shapes : some functions to help you create basic shapes (circle, square, triangle, rect, and with/without edges)
• Waves : some functions to help you making gradients ou lerp values from A to B with a precise wave shape.
• Transform : nodes to transform space and time. Can't do coffee at the same time.
• Other : wip functions without a type (like amod).

All nodes are designed the same way :

• 0-1 value mean 0 for nothing and 1 for max default value. ex : for a circle 0 for radius means an invisible cricle and 1 a big circle with edges touching the uvs.
• when an input "UVs" can be used, you need to add a node Texture Coordinate or a transformation of uvs.

Most of shapes are designed on this first node. The pivot can change the center of the shape. UVs means a representation of space and can be used with Texture Coordinate. Radius means the size of the circle.

Thanks to Flopine & Koltes, Amod function is a way for duplication shapes in a circle. It uses polar coordinates. For simplification : you don't duplicate the shape, you "duplicate" the space where the space will be created.

Add Transform type Remove Rotate2D node (useless), use Rotator instead with value mul PI Move amod to Transform type Add 2 nodes : Xmirror & YMirror
