v0.42

A float or vector field that looks up values from a texture.

Texture is centered at 0,0 with coordinates from -0.5 to 0.5.

Parameters

Name	Description	Regular Handling	Read-Only Handling
Enable
Coord Type	The type of coordinates used for UV mapping.
Auto: 1D: Uses the 1D coordinate as U and 0 for V. 2D: Uses the provided 2D coordinates. 3D: Uses the specified `Axis` to choose which axes to use for U and V.
Return Type
Float: Vector:
Contexttype	When used for materials, set to MaterialContext, otherwise use Context.
: : : : :
Plane	When using 3D coordinates, the axis that faces the plane used for UV. This is not used when a UV field input is attached.	Runtime	Baked
YZ: U=Y, V=Z ZX: U=Z, V=X XY: U=X, V=Y
Translate	Offsets the UV coordinates.	Runtime	Baked
Scale	Scales the UV coordinates.	Runtime	Baked
Texture	TOP used for the texture.
Extend Mode	How to handle UV coordinates outside the 0..1 range.	Semi-Baked	Semi-Baked
Hold: Zero: Repeat: Mirror:
Coord Mode		Baked	Baked
UV [0-1]: Pixel [0-n]:
