Shader nodes
Build a picture from nodes. Values, colours, gradients, noise, maths and mixes, wired into one image.
Shader nodes live in a NodeContent's graph and flow into its OutputNode, which makes the picture. The graph becomes one shader and redraws when a value, a wire or an input picture changes.
ShaderNodeThe building blocks of a node picture: values, colours, gradients, noise, maths and mixes, wired together into one image.OutputNodeThe last stop of a node picture: whatever reaches it is the image.ValueNodeOne number to steer many nodes: type it once and wire it everywhere.ColorNodePick a colour once and hand it to every node that needs it.UVNodeKnow where every pixel is, and turn its place in the picture into gradients, stripes and masks.ImageNodeBring a picture into a node graph to tint it, move it or mix it with everything else.GradientNodeStart from a smooth ramp: linear, diagonal, radial or spherical.NoiseNodeSmooth noise for clouds, dirt and grain, as fine or as coarse as you like.MathNodeDo the maths between nodes: add, multiply, compare, wrap or wave any number.MixNodeBlend two colours or pictures in any of Photoshop's blend modes, by as much as you like.RampNodeTurn a grey value into colour: map noise or a gradient onto a ramp between two colours.SeparateNodePull a colour apart and use its red, green, blue or alpha on their own.CombineNodeBuild a colour from four numbers, each wired from anywhere in the graph.MappingNodeSlide, spin and stretch a gradient, noise or picture without touching the node that makes it.
