Tear and roll part of a paper?

Recommended Posts

Posted (edited)

I'm trying to figure out how to animate a paper reveal with torn edges while the torn part rolls up?

I tried using a path deform along a line with a spiral at the end, but that didn't really give the appropriate effect.

I need to lift part of the grid out, not roll the entire grid.

Does anyone have any tips to match the reference?

A little better concept here of isolating a single fracture element and applying a bend.

This gets me closer, but the bend generates intersecting geometry. Is there way to tell the bend to shrink a little as it rolls up?

Based on your file I was able just to adjust the capture direction slightly to get it to curl up with no intersections. This will break eventually though if you need it to curl alot

with a divide sop and a fuse to accompany the bend, I could push it to about 1200 degrees before it broke.

Thank you, that helps a lot.

I discovered that if I leave the bend value as 1220 and animate the x-axis of the Capture Origin, that I get a nice rollup.
