MaskPin
MaskPin is a lightweight native After Effects effect for mask-based perspective pinning.
Instead of starting from the full comp or layer bounds, MaskPin fits four perspective pins directly to your mask area in one click.
Corner Pin starts from the comp. MaskPin starts from your mask.
MASKPIN
Mask-Based Perspective Pinning for After Effects
Draw a mask. Select it. Start pinning.
Corner Pin starts from the comp. MaskPin starts from your mask.
Mask Selection &
Renderable Guides
Select the mask you want to use, and MaskPin automatically fits the pins to that selected mask. You can also render the mask outline, vertices, corner pins, and connecting frame directly into the final output.
MaskPin v1.2.0
The new update adds mask selection for multi-mask layers and a complete renderable-guide system for creating technical overlays, breakdown graphics, HUD visuals, and tutorial-style outputs.
Select a Mask. Pins Fit Automatically.
On layers containing multiple masks, select the mask you want MaskPin to use. As soon as you choose it, MaskPin automatically fits the corner pins to that mask — no extra Fit Pins To Mask click is required.
Render Guides in the Final Output
Render the selected mask outline, original mask vertices, corner pins, and connecting frame directly into your final image or animation.
Customize Guide Color, Width, and Opacity
Match the rendered guides to your design with independent Guide Color, Guide Width, and Guide Opacity controls.
Independent Pin Size and Five Render Shapes
Adjust the interactive Pin Size separately from Render Pin Size, then choose Square, Circle, Triangle, Plus, or X for the rendered pins.

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.

Fit Pins To Mask

Perfect for angled screens, phones, laptops, posters, signs, billboards, and perspective surfaces.
Composition Viewer Handles
Fine-tune the result visually by dragging the custom handles directly in the After Effects Composition viewer.
Native effect. No panel. No precomp workaround.
MaskPin is a lightweight native After Effects plugin. No CEP panel, no external script, and no required precomp workflow. Everything runs directly inside the effect.

Built for setup — not tracking.
