It looks like a sheet of paper being lifted from one corner, exposing what lies beneath. The curved edge and shadow suggest a physical page turn.
`corner` defaults to bottom-right and selects the peeling corner. `amount` defaults to 0.2 and ranges from 0 to 1 for the peel progress; `radius` defaults to 0.2 and ranges from 0.02 to 0.4 for curl tightness. `shading` defaults to 0.55 and ranges from 0 to 1 for underside shading, while `highlight` defaults to 0.4 and ranges from 0 to 1 for the sheen along the curl.
Place an image or video beneath it; a lower incoming scene can show through the peel. A broad radius makes a gentler curl and a smaller value tightens it. Strong highlights and shadows can make flat graphics feel heavy.
When to use
Use it for a page or card reveal, a transition that uncovers a photo, or paper-like graphics. Avoid it for fast, minimal app transitions or simple text changes.
