Channel Sampler

Updated: 14 Aug 2025

This shading node outputs one of the input values from a given pixel.

Method #

This shading node allows you to extract one of the input values from a given pixel. Shading nodes are applied to material texture channels to generate textures procedurally while rendering.

Parameters

Attributes

These properties control the core behaviours of the node.

Parameter	Details
Channel	The input channel. World Position : The pixel’s world position. Object Local Position : The pixel’s object-local position. Texture Coordinate : The pixel’s UV. Normal : The pixel’s normal value. Vertex Colour : The pixel’s vertex RGB colour values. Vertex Alpha : The pixel’s vertex alpha colour values. Albedo Colour : The pixel’s albedo colour values. Alpha : The pixel’s alpha. Baked Diffuse Colour : The pixel’s baked diffuse colour. Specular Colour : The pixel’s speculuar colour. Roughness : The pixel’s roughness. Metallicness : The pixel’s metallicness. Emissiveness : The pixel’s emissiveness. Ambient Occlusion Texture : The pixel’s ambient occlusion texture value.. Composite Lighting : TBC. Composite Occlusion : TBC. Depth : TBC. Camera Distance : TBC. Instance Index : TBC. Screen UV : TBC. Camera Eye Image : TBC. Field Density : TBC. Field Temperature : TBC. Field Fuel : TBC. : TBC.
Preview In Viewport	Passes this node’s output to the destination material as a colour channel, so it can be previewed more easily.
