Vector image under clipping mask in Fresco become pixel in Illustrator

[Yushan Hsiao]

I created a vector image in Fresco on my iPad Pro, exported as pdf file, and opened in Illustrator on my Macbook Pro 2016.  

For some reasons, some portion in my image remained vector, but some turned into pixel.  

Not sure if it is because of the clipping mask.  Is this a bug on Fresco side?

If this is a bug, is there any suggested way to work around on this issue?
The way I could think of is using the eraser for images under cliping masks, but that would be a lot of work. Any suggestion?

In my experience,  if you want it to stay vector,  you'd have to leave the vector linework by itself.  If you do clipping masks or use regular pixel brushes, its going to rasterize everything.

When you create a clipping mask in Fresco, you get a warning dialog box that says, "In order to mask this layer, you need to convert it to a pixel layer. This may affect the scalability and other characteristics of the layer."

So, I think the answer to your question is, clipping masks over vectors in Fresco are converted to pixels as soon as they are created. There is no vector to export once you've created the mask, it is now a pixel layer.

Hi, I have the same issue - however, clipping masks with vectors remain as vectors when I opened on Illustrator Desktop. But, as per the initial post, I am getting some layers being rendered as pixels when I bring them into Illustrator Desktop. Others have retained their vector status. I double checked in Fresco and within it they are most definitely vector?

I experience the same issue. Would love it if fresco kept vector clipping masks as vector in illustrator.
