Adam M. When setting a texture alpha mod other than 255 and also specifying a flip mode in the software renderer, the rendering fails. When the texture has an alpha channel, it becomes invisible when flipped. When the texture does not have an alpha channel, it is flipped but the colors are wrong: the alpha mod makes the texture darker rather than more translucent. 0) Initialize a software renderer. 1) Load 16-bit 565 or 32-bit texture. 2) Set texture blend mode to BLEND. 3) Set texture alpha mod to 150. 4) Draw the texture flipped horizontally and/or vertically. |
