Well I have a curved mesh that I want it to be straight.

I wanted to know what is the best and fastest way to straighten this mesh.

The mesh is already bent and I now use the armature and some sculpting to make it straight , is there any plugin or node group that can help me make these ornamentals with curves?

here is the other one enter image description here

  • $\begingroup$ @HarryMcKenzie Nope ! , i uploaded the blend file , i want something to reverse the curve modifier $\endgroup$

    $\begingroup$ Curving a geometry is destructive in a sense (I don't mean procedural vs destructive workflow here), some information is lost, like with a blur. Philosophically speaking, some people argue the information is never lost (with a controversy regarding black holes) and so theoretically the original shape could be restored, maybe with some damage due to a limited float precision… However, reversing some processes is just impractical. What makes a night and day difference is the info about the modifier initially applied - having such data opens some reasonable, practical, reliable strategies. $\endgroup$

    $\begingroup$ I tried with a cruve that has 2 shapekeys, a flat shape and one that follows the leaf bend, in order to try a retro-curve operation, but no good success so far :( $\endgroup$

So your suggestion to use armature gives an excellent result, you should write your own answer, my test:

My try with lattice:

You could try with a Lattice modifier, make the lattice cage flat, subdivide it a bit on its length, then deform it to straighten the leaf:

Quick result (on the right the final goal):

  • $\begingroup$ Thanks a lot but this isn't exactly what i wanted , you see when the mesh is straight we can easily curve it with curve modifier not reverse , if i want to do such thing other parts of the mesh will be deformed so bad that i can't use it at all , i''ll upload blend file $\endgroup$

  • $\begingroup$ So , i have added another one of my flowers there as you can see it is not possible to decurve it with lattice , although your method is good i appreciate your effort $\endgroup$

    $\begingroup$ It seems impossible to do it properly, what is your situation exactly? If you had straighten versions, you should have kept them of course... $\endgroup$

    $\begingroup$ So I've tested your idea and it works fine, I've edited my answer but you should write your own answer $\endgroup$
