#ue 5

so everything i figured out at home translated beautifully to unreal

and i can't believe it worked!

I'm keeping the b/w version in to visualize what you're masking, and it feels pretty nice to play with the sliders

there's just one problem...

as you might've noticed, an object completely masked in black still appears doubled because it is directly next to a white pixel

so now the question stands:

how can we "grow" the black sections exactly 1 pixel left and right?

my current idea is to multiply every pixel with its neighbors, this way any white pixel (val 1) next to any black pixel (0) turns black. or even if it's close to black, it will adopt the value of that pixel. multiplying pixels like this can only darken them. but that feels inexact and potentially costly? i wonder what kind of noises this might generate? not to mention I have no idea how to get this to work (i have very little experience scripting)

maybe some kind of blur?

...

ok wait. this is a really stupid idea, but it just might work:

We duplicate the entire depth pass, move it over 1 pixel, and multiply that with the original.

we might have to do this twice (per L + R)

this feels way more costly processing-wise than the kernel thing, but it will probably take less time to figure out
