Draw a mask. Click Fit Pins To Mask. Start pinning.
Corner Pin starts from the comp. MaskPin starts from your mask.
Stop dragging corner pins from the comp edges.
Traditional corner pin workflows usually start from the full layer or composition bounds — even when your real target is a smaller masked area.
That means manually dragging each corner into place, matching the mask by eye, and repeating the setup when the mask changes.
MaskPin removes that setup step by fitting the pins directly to the mask area.
Three focused tools. One clean workflow.=100%Fit pins directly

4-point mask vertices.Drag pins directly in

Apply MaskPin, click Fit Pins To Mask, and the four perspective pins are placed directly around your mask area.

Fine-tune the result visually by dragging the custom handles directly in the After Effects Composition viewer.

Built for setup — not tracking.
MaskPin is not a full tracking or match-moving system and does not replace Mocha or planar tracking tools.
It is built for one specific workflow: fitting perspective pins to a mask area so you do not have to start from the comp or layer edges.
