Hi
I have created two frame buffer objects, one is used to render the 3d world and one is used to render the ui. The strategy being if I change the ui I don’t want to re render all the 3d if I don’t have to. My problem is not is how to combine these such that I can display them both. The ui frameTexture has transparency where it is not drawn.
At the moment I have another shader where I try and render both frame textures on to a quad, one after each other. But this only didsplays one, probably due to them haing the same depth.
Is there a better strategy for doing this?
