v0.36

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

• 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:
• : 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.
  • YZ: U=Y, V=Z
  • ZX: U=Z, V=X
  • XY: U=X, V=Y
• Translate: Offsets the UV coordinates.
• Scale: Scales the UV coordinates.
• Texture: TOP used for the texture.
• Extend Mode: How to handle UV coordinates outside the 0..1 range.
  • Hold:
  • Zero:
  • Repeat:
  • Mirror:

Inputs

  • Coordinate Types: float vec2 vec3 vec4
  • Context Types: Context MaterialContext CameraContext LightContext RayContext ParticleContext
  • Return Types: vec4
