Shader node reference

95 nodes across 7 categories, for building materials as graphs. How to use them is in Material graphs.

Port types are float, vec2, vec3 and vec4. A vec3 carries a colour or a direction; connecting mismatched widths is handled for you where it makes sense.

const

Fixed values you type in.

Node	What it does	Inputs	Outputs
constFloat	A fixed number.	—	out:float
constVec3	A fixed triple.	—	out:vec3

input

Where values come from: UVs, the surface normal, time, textures, the instance being drawn.

Node	What it does	Inputs	Outputs
cameraDistance	How far this pixel is from the camera. Good for fading things out with distance.	—	out:float
chromaKey — Chroma key	Removes a colour, turning a green screen transparent.	color:vec3, key:vec3, similarity:float, smoothness:float, spill:float	rgba:vec4
instanceColor — Instance Color	The tint that copy carries.	—	out:vec3
instanceId — Instance ID	Which copy of an instanced object is being drawn — feed it into a hash to make every copy different.	—	out:float
materialRef — Material	Pulls in another material as a starting point.	—	out:vec3
normal	Which way the surface faces.	—	out:vec3
normalMap	Applies a normal map, adding surface detail without more geometry.	uv:vec2, strength:float	out:vec3
paramColor — Param (color)	A colour exposed the same way.	—	out:vec3
paramFloat — Param (float)	A number exposed as a material setting, adjustable without editing the graph.	—	out:float
position	The point on the surface, in the object’s own space.	—	out:vec3
sampleLod — Sample Texture LOD	Samples at a chosen blur level — cheap softness.	uv:vec2, lod:float	rgba:vec4
screenUv	Where the pixel is on screen rather than on the surface.	—	out:vec2
texelFetch — Texel Fetch	Reads one exact pixel, unfiltered.	texel:vec2	rgba:vec4
texelSize — Texture Size	The size of one pixel of a texture, for neighbour-sampling effects.	—	size:vec2, texel:vec2
texture	Samples an image at some coordinates.	uv:vec2	rgba:vec4
time	Seconds since the scene started. Anything that moves starts here.	—	out:float
triplanar	Projects a texture from three directions at once, so untextured or stretched geometry still looks right.	scale:float, blend:float	rgba:vec4
uv	The texture coordinates of the pixel being drawn — the basis of most patterns.	—	out:vec2
viewDirection	The direction from the surface toward the camera.	—	out:vec3
worldPosition	The same point in world space — use it for effects that stay put as an object moves.	—	out:vec3

light

Lighting terms you can shape yourself.

Node	What it does	Inputs	Outputs
fresnel	Stronger at glancing angles — rim light, force fields, the sheen on a car.	power:float, normal:vec3	out:float
