vector – cinema4d to illustrator export options

I’m trying to export a cinema4d scene file into illustrator.
i need to create the vectors for the cubes i have in c4d.
but when I export the result is as in picture
(top is an actual screenshot of the render – bottom is the illustrator exported file)

Is there any way to output the cubes as i see in the render? I mean, the vector files turns out to be almost perfect.. the “front face” of the cubes, depending on the rotation of them, will sometime disappear (you can see some cubes look like if they’re empty).
is there any way through some kind of settings to achieve the same result of what i’m seeing in c4d (solid cubes instead of empty ones)??

thanks
