im attempting to edit the icons that show your teammates on the map(theya re too big)...i need to know what color i should choose as a background color(so its tansparent), and also how to save it(additive/alphatest/normal/indexalpha)...thx in advance

bump...somoene must know how to make the background transparent :/

Put the background white but if you have white in your icon put it light grey. Then save it as alphatest 255 colors. Dont forget to check Alphatest transparency in the option

Transparency is the last color in the pallete, and it's best to use something bright, like blue or green, so you don't accidentally make part of your sprite the same color.
