I've always run into this issue, and diving into it a bit more today, I can't seem to figure out 'HOW' to stop the PS6 vanishing tool from pixelating my website mock-ups!
I often mock-up web screenshots on devices for my portfolio and clients. (Perspective monitors, smartphone devices etc.) and I typically use the vanishing tool to do so. Problem is, the vanishing tool forces me to rasterize my image before its able to be placed on the grid, rather then allowing me to transform the vector versions of it. This results in a lot of jagged edges and major quality loss on type.
My question is: is there a way to use the vanishing point tool with vector (or grouped) objects? If not, is there a better way for me to make these transforms for my mock-ups? Using the skew / transform tool proves to be time consuming and inconsistent.
