i write to 3 fbo color attachments at the same time. i’d like to enable blending for the first attachment, but not for the others. is this possible? or will i have to render separately?
A quick Google search shows the EXT_draw_buffers2 extension enables you to toggle blending on/off for each buffer separately.

Seems this is a GeForce 8 extension.
