    How to layer masked surfaces?

    by TinyMapper » Mon Jan 28, 2019 2:42 am

    Hey MM community,

    I am trying to project to a screen with a non-standard (i.e. not round, spherical or triangular) section in the middle but I am having a really hard time figuring out the right way to layer them.

    With standard surfaces I can just layer three on top and they will show up independent of each other like this:

    However, if I try apply a Mask in order to trim Quad 2 (red) to the section at hand I get:

    Where I would like to see just Quad 2 trimmed to size:

    I've messed around trying to use the multiply command as well but that runs into the same issue. Anything below the layer I am trying to cut falls into the same filter. Is there a way to apply a mask to only one specific layer? What is the standard workflow for creating surfaces of a custom shape?

    Any help would be much appreciated!
    Thanks,
    TinyMapper

    you can apply a mask INDIDE a quad.
    Create a quad surface, scroll down in the inspector panel, the'res a mask option.

    Hey franz!

    Thank you so much! I was aware that masks within surfaces existed but my screen consists of a lot of circles so it didn't occur to me to try using quads. And it turns out that circles don't support layer specific masking.

    I have created a quad instead and am now happily projecting. Thanks again. : )
