Hi, Recently I have found there are many games using a jpg and a tag file for their sprites ! As you know , we can use a png file with alpha-channel to transparent them on the screen . This is used for sprites in a game specially . But I have found these games only use jpg and tga file ! And it seems the tga file is only a black-white image ! So ,the questions is : How to use a jpg and a tga file to work together like a png file ? --Especially in HGE . Thanks for your time

Load jpg as a normal image, then load the monochrome TGA into the alpha channel of the jpg you loaded.
