So I decided to try to make a skin from scratch, y'know, editing it into a 64x64 image and such. But when I rendered it into the launcher to see if anything mismatched, it was all white! If anyone knows how to fix this can you help me? My skin is down below (A rough draft anyway).
There is no alpha channel on this image. The parts that you interpret as "blank" on the image you linked are just white, and the game interprets that as a layer I think. Try editing it and using an eraser tool that doesn't just use a background color.
