Corner Pin

Node icon
Transform

Applies a perspective warp by repositioning the four corners of the image. Place artwork onto surfaces, or correct the perspective on a distorted photo to produce a flat, rectangular result.

Corner Pin supports two workflows using the same underlying transform:

Place (“forward”): Drag the destination corners onto an angled surface to composite flat artwork onto it — the classic billboard, phone screen, or book mockup.

Correct (“inverse”): Set the source corners onto a perspective-distorted region of your image (a tilted sign, document, or facade), then use Straighten in the preview toolbar to make the destination axis-aligned. The node flattens that region into a rectangle. Use Crop to Destination output mode to emit a tight crop at the corrected size with no downstream Crop node needed.

The Source | Destination toggle in the preview toolbar switches which set of handles you are editing. In Source mode the preview shows the input image so you can accurately place source corners on the distortion. In Destination mode the preview shows the warped output.

When a background image is connected, the Output Mode selector lets you composite the warped result directly onto the background, with Blend Mode and Opacity controls in Composite mode.

Filter

InterpolationChoice
Default: Bilinear

Resampling filter

  • NearestNo interpolation, so hard pixel edges are preserved. Best for pixel art.
  • BilinearSmooth blending between pixels, with good general-purpose quality.
  • LanczosHighest quality with sharp detail preservation, best for final output.

Output

Output ModeChoice
Default: Composite
  • Warped OnlyOutput only the perspective-warped image on a transparent background.
  • CompositeComposite the warped image onto the connected background.
  • Crop to DestinationEmit a tight crop sized to the destination quad bounding box, so an unwarp produces a clean flat asset without a downstream Crop node.
Blend ModeChoice
Default: Normal Range: Normal / Multiply / Screen / Overlay / Linear Dodge (Add) / Subtract / Difference / Hard Light / Soft Light / Darken / Lighten / Color Dodge / Color Burn / Exclusion / Hue / Saturation / Color / Luminosity
Composite mode only

Blend mode when compositing

OpacityNumber
Default: 1.00 Range: 0.00–1.00
Composite mode only

Composite opacity

Usage Tips

Section titled “Usage Tips”
  • Use the interactive corner handles in the preview for visual placement.
  • For perspective correction: switch to Source mode, place the four source corners on the distorted region, then press Straighten to make the destination rectangular.
  • Use Crop to Destination when you want a tight crop of the corrected region as the output rather than the full frame.
  • Connect a background image and set Output Mode to Composite to place artwork directly onto a surface.
  • Corner values beyond 0-100% let you extend the warp beyond the original frame.
  • Use Lanczos interpolation for the highest quality output on final renders.
