Don't know the first thing about scripting or VEX, but I needed to fix the symmetry of a character without destroying UV's or other attributes.

I've been looking for a tool to fix symmetry based on a symmetry map like in Softimage XSI since it's very easy to screw up symmetry in Houdini because it's not a global setting but has to be toggled on for every single SOP every time a new one is created.

But it seems the only way to fix symmetry in Houdini is to mirror the mesh and thus destroying a lot of attributes like UV's, envelopes and such.

So with a little help from ChatGPT I created a HDA to fix symmetry in X, Y or Z axis without affecting the UV's or other attributes by creating a "Symmetry map" from the original mesh, and to my big surprise it actually works !

So if anyone needs to fix symmetry like this, I attached the HDA.

Besides the non-symmetrical mesh it needs the original mesh that hasn't been edited to create a "symmetry map".
