Inherits: VisualShaderNode < Resource < Reference < Object

Performs a texture lookup within the visual shader graph.


Performs a lookup operation on the provided texture, with support for multiple texture sources to choose from.


enum Source:

  • SOURCE_TEXTURE = 0 --- Use the texture given as an argument for this function.
  • SOURCE_SCREEN = 1 --- Use the current viewport's texture as the source.
  • SOURCE_2D_TEXTURE = 2 --- Use the texture from this shader's texture built-in (e.g. a texture of a Sprite).
  • SOURCE_2D_NORMAL = 3 --- Use the texture from this shader's normal map built-in.
  • SOURCE_DEPTH = 4 --- Use the depth texture available for this shader.
  • SOURCE_PORT = 5 --- Use the texture provided in the input port for this function.

enum TextureType:

  • TYPE_DATA = 0 --- No hints are added to the uniform declaration.
  • TYPE_COLOR = 1 --- Adds hint_albedo as hint to the uniform declaration for proper sRGB to linear conversion.
  • TYPE_NORMALMAP = 2 --- Adds hint_normal as hint to the uniform declaration, which internally converts the texture for proper usage as normal map.

Property Descriptions

Default 0
Setter set_source(value)
Getter get_source()

Setter set_texture(value)
Getter get_texture()

The source texture, if needed for the selected source.

Default 0
Setter set_texture_type(value)
Getter get_texture_type()

Specifies the type of the texture if source is set to SOURCE_TEXTURE. See TextureType for options.
