Thank you Jack, Indeed! I was aware of the GL separate object but didn't know that I had to use the same approach for pixes. Somehow I feel this could be mentioned in some GEM docs (but where?). Thank you for your kind reply! I am curious how it could be done using shaders, but am quite happy the way things are working now!
