Hi, i created a test file to compare how alpha blends in different situations, especially "color opacity vs layer opacity". The file contains 16 tiles 4 "large" tiles showing top: vector shapes, bottom: fill layers, left: raw, right: copy of left rasterized & tim 4 "small" tiles, showing left: red left color opacity   / layer opacity : 50 / 100, right 100 / 50 blue top 50 / 100
