Hello,
Using this extension, can you practically read/write from/into multiple render targets bound to the current framebuffer on Adreno 530?
From what I see I cannot read from the frame buffer's color attachments from 1 to n (only 0). Sampling from them returns the color of the color attachment 0. However you can write to them, thus overwrite their color.
If it normally works is there something special have to be done? I, for example created a normal FBO with a couple of color attachments, render a quad,assign some values to color of the render targets, then another quad to programmatically blend (in the shaders) with the last colors and declare inout the fragment outputs.
