Reduce Curve Deformation Currently I am working on an animation that requires a scroll opening up. I added a Curve Modifier with a spiral curve to both parts of the scroll mesh, then I added another Curve Modifier with another curve to the mesh.
The result is this when it's only a bit open (good):



The result is this when it's halfway opened (bad):



How would I keep the wrapped-up part to stay circular like in the first image? Thanks in advance!
I've never had much joy combining two curve modifiers - not even sure what your set is - perhaps curve following path? As curves do essentially modify, they work fine with things like cables and planes, but will distort objects especially around tight corners.

The example below I set up with a Nurbs curve with three Hooks: One to hold the centre form and the other two to animate. There is not much animation just a bit of rotation and placement. If you wanted the scroll to open more, you could just scale it on one axis.

Maybe not the answer you were looking for but think it could be usable...
