Hello,
This is a test where I inputted a Checker 1 into a mask with tiling 1x1. Texture Resolution is 128x128. Tested all filtering options and I still get blurriness between the black/white. I want to create a 1 bit alpha mask, I should see nice crisp lines for the checker.
SOLVED: screenshot was taken from the viewport which does not display 1 bit accurately. Export the output was correct.
