Oh, I wasn’t using that no. Just Merged projects with an Illustrator 8 file. I tried installing the plugin you suggested, but couldn’t make it work here.
In C4d, the problem seems to be with the Spline Mask. These letters are imported in a group due to their holes. So whenever I apply the Spline Mask they get these rough edges. I searched “Show Help” but what they suggest doesn’t worf for me either (“change the spline interpolation type to, for example, Natural and increase the number of vertices”).
I attach the Illustrator file here if anyone can find a way to offer me a hand!
Thanks Jim for your fast reply!
