Check that the anchorpoint- and position- values are both on whole numbers, expecially if your exported assets may have an odd-number of pixels in their dimensions
For example, if you have a layer thats 1001×1001 pixels, it’s default anchorpoint will be at theat layer’s centre: 500.5, 500.5, if you now position that layer at 960,540 every pixel is actually shifted half a pixel and needs to be anti-aliased.
you’d either need to shift the anchorpoint or the position by 0.5 pixels
