Invert

Node icon
Color

Inverts image channels, flipping colors to their complement per channel or all at once.

The Invert node applied to a source image: original (left) and result (right).
Side-by-side comparison: the original image on the left and the same image after the Invert node on the right.

Invert produces the photographic negative: red becomes cyan, white becomes black. Red, Green, Blue, and Alpha invert independently; Alpha is off by default so transparency is preserved. On a single-channel image the toggles collapse to one Invert control.

Texture sets

Section titled “Texture sets”

On a texture set or a library, a Map row at the top of the panel picks the one map Invert edits, such as the Roughness, and every other map passes through untouched. Inverting the Roughness turns it into a smoothness map. See Changing one map.

Color

MapChoice
Default: Base Color
Texture set or library wired

Which map of the texture set this node edits. Every other map passes through unchanged. Shown while a texture set or a library is wired

  • Base ColorWork on the set's Base Color. The first map for the color and tone nodes.
  • NormalWork on the set's Normal. Offered on Normal Map (rescale its intensity) and the nodes that read a map into a selection; a color node never edits a direction.
  • RoughnessWork on the set's Roughness, a linear 0 to 1 map with one channel.
  • MetallicWork on the set's Metallic, a linear 0 to 1 map with one channel.
  • Ambient OcclusionWork on the set's Ambient Occlusion, a linear 0 to 1 map with one channel.
  • HeightWork on the set's Height, a linear map that can pass 0 and 1.
  • OpacityNever offered: the Opacity is the set's cutout, which Mask Apply edits.
  • EmissiveWork on the set's Emissive color.
InvertToggle
Default: true
1ch input only

Invert the grayscale channel (255 - value).

Shown when a single-channel input is connected.

Invert RedToggle
Default: true

Invert the red channel (255 - value)

Invert GreenToggle
Default: true

Invert the green channel (255 - value)

Invert BlueToggle
Default: true

Invert the blue channel (255 - value)

Invert AlphaToggle
Default: false

Invert the alpha channel (255 - value). Off by default to preserve transparency

Mask

Mask FromChoice
Default: Luminance
Color image connected to the mask input

How the connected color image is read as a mask

  • LuminanceRead the image's brightness as the mask. The default.
  • AlphaRead the image's transparency as the mask.
  • RedUse the red channel as the mask.
  • GreenUse the green channel as the mask.
  • BlueUse the blue channel as the mask.
Mask FitChoice
Default: None (native size)
Mask connected

How the mask is sized when it doesn't match the image

  • None (native size)Center the mask at its native size, with no resizing. Unmasked regions are unaffected.
  • StretchStretch the mask to exactly match the image dimensions. May distort the mask shape.
  • Fit (letterbox)Scale the mask to fit inside the image, preserving aspect ratio. Letterboxes where needed.
  • Fill (crop)Scale the mask to fill the image, preserving aspect ratio. Crops edges if aspect ratios differ.

Usage Tips

Section titled “Usage Tips”
  • Turn off Red, Green, and Blue and turn on Invert Alpha to flip only the transparency.
  • Connect a mask input to invert only specific regions of the image.
