Hello,

I'm trying to find out how to get a backbuffer for attached shader found in the web (http://glsl.heroku.com/e#8849.0), it seem I couldn't get alpha channel in gemframebuffer's recursion, any idea?

Hello Patrice,

I just added a line at the begining and an other one at the end of fractalFeedback.frag to change the alpha for the feedback.
I also change the texunit ID backbuffer to 0 in the patch.
You can change alpha feedback with the number box i added in the patch.
Hope it helps.
