Hi,
I am having the exact same issue and I feel upset about that.
I know it’s been quite a long time but did you find any solution about it Jerry ?
If you have created your text correctly, it will render perfectly and will be sharp.
I did the test on a Quicktime Animation rendered file and I’m sorry to say no it is not sharp. Of course, it is not that obvious, but I want my vector layers to be as sharp as they are in 2D.
(I might have a workaround about this when dealing with AI file. I just copy and paste my path from Illutrator to After Effects on a shape layer. I did this with text, turned the layer and 3D and hopefully there was no change on the edges, but it’s time consuming and boring…)
