1:04:19d7 If the contour of your entities wasn't antialiased, you could have used the depth buffer and reverse the render order for the entities being faded (front to back), but alas, it is hard to do properly with the alpha blending around the contours

1:05:50evraire You mentioned rendering to an offscreen buffer then compositing as one means of getting the desired alpha effect, but you also mentioned something along the lines of using a "fragment list"? could you please elaborate a bit more on that approach?
