19:46 finger563 question: how can i get the alpha channel correctly from my framebuffer?
19:46 finger563 i'm doing a readpixels into a buffer while hte FBO is bound
19:47 finger563 and i'm getting RGBA, but the alpha seems to be merged into my RGB values already

21:28 finger563 anyone here?
21:30 jvcleave you have ofEnableAlphaBlending() on?
21:35 finger563 yea i do, and i've tried with both on and off
21:36 vade joined #openframeworks
21:39 finger563 the issues is that i'm writing (with my shaders) rgba into gl_fragcolor
21:39 finger563 where the rgb values are directly from the camera (unmodified) and the alpha is the result of my calculations
21:40 finger563 but when I do a read pixels on it, i'm getting the alpha has already corrupted (modified) my rgb values in addition to being present in its own alpha channel
22:26 jvcleave any have you tried doing it in draw() as opposed to update()? wondering if it is the programmable renderer bug
