I am using 2.28. I have converted from a font to curve to mesh then warped the mesh. I am getting a jagged result after the warping. It looks like the mesh is getting triangle-ized. Perhaps removing triangle would help but I can’t find anything on it when I seasrch around.
That’s because when blender faces it, it just gives it a ‘fill’. which is made out of trangles, and is no good for warping. You have to erase the faces and put them back in manually in the form of squares. ( well, less triangles anyway. )
