How to make Roughen edges effect scale to remain constant in 3D

[John Cuevas]

Moving the layer on z space doesn’t really work with roughen edges. There’s a couple of tricks you can do to get it to stick, but nothing that will allow you to move along z-space and maintain sharpness—unless you create incredibly large layer, apply roughen edges and then scale down only, never scale past 100%

Courtesy of Kevin Camp:

roughen edges doesn’t really stick to the layer like many other effects. it has it’s own offset value that kind of maintains a center point for the fractal texture that is distorting the layer…

you can use an expression to link the offset to the layer’s position so that they move together (and apear static).

adding this expression to the offset property in the roughen edges effect would work for position:

transform.position*400/effect("Roughen Edges")("Scale")

if you adjust the layer’s position the roughen edges should stick. it will not work with rotation or scale, though the layer’s scale could probably get worked into the expression.

an easier way is to add the transform effect after the roughen edges effect, and use the transform effect’s properties to do the animation. then it sticks no matter what.
