Hi Cow !
Is it possible to save a transformation (warp or mesh) as a preset ? Or can I create action to save myself from applying the same transformation to hundreds of objects ? Smart objects getting slower as included layers multiplying; very very slow for me at this one, so I try to find an other solution. Do you have any idea about this?
Yes you can create an action in Photoshop. Just don't forget to apply the transformation within the recording of the action (after I put in my amount and see the preview of the warp, I just switch to the move tool, then I get asked do you want to apply the transformation, click yes).
A simple solution for type layers only
Alt-drag a copy of the warped type layer, then doubleclick on the type, and then change your letters.
