Checkerboard cells fade in sequence until the scene disappears in grid pieces. The regular pattern creates a noticeable beat.
`progress` defaults to 0.5 and ranges from 0 to 1. `blockSize` defaults to 0.1 and ranges from 0.02 to 0.5 to change the square size. `softness` defaults to 0.15 and ranges from 0 to 1 to soften each fade; `invert` defaults to false and reverses the cell order.
Place an image or video beneath the effect. Put the incoming scene on a lower layer and animate progress to use it as a transition. A large block size can look coarse, while low softness creates crisp edges that make text appear fragmented.
When to use
Use it for scene changes with a grid rhythm, graphic titles, or a pixel-like transition. Avoid it when copy and tables need to remain fully readable.
