  • how do you change the thickness of the alpha boundary line?

    Hi all,

    When using the rotobrush or doing any masking and you’re previewing using the alpha boundary line (the magenta outline which shows you the edge of your mask)- I find the line is too thick and makes it harder to quickly make accurate adjustments without having to toggle between other mask views.

    So, can someone point out to me how to adjust the thickness of the line?

    Cheers

    Ah yes – thanks, zooming does help some but stupidly, the boundary line also increases in size.

    What would be most handy, would be to be able to toggle view what you’re rotobrushing in front of the background you’re going to finally put it into.

    Cheers!
