I earlier posted some stuff on motion-blur, and followed the instructions I received. I’m generating about 4 texture-mapped quads per scene, each with a different alpha-level from 0.25 to 1.0. Here’s a snip:
glBlendFunc sfSrcAlpha, dfOneMinusSrcAlpha
For i = 1 To 4
glColor4f 255, 255, 255, 0.25 * i
And this is the effect:
Anyone recognize what’s going on (read: wrong) there?
