If you’re using .png and the file contains an alpha layer as background you click “UseAlpha” in the Texture tab in F6. If not then use “CalcAlpha”. In the MapTo tab in F5 (for both Use and Calc) you need to map it to Alpha. If using CalcAlpha that setting (white) will calculate Black, and degrees thereof, as the color to use as alpha. If you click it again (yellow) it will use white and degrees therof.
