All text and graphics look fine in ai but on export to create a png the text which has been typed on a path is distorted or the wrong size. I am not aware of changing any settings but the previous day I had been experementing with the new features in 3D and materials, in doing so and whilst using text I downloaded a materials file from the community settings.
It weird. I took and old doc and on export everything was fine. I then changed the text font and the problem resurfaced. I ended up just expanding the text to create an object and then all exports were ok.
