Hi Anton
For example: I have the first camera - this is the main scene and the second
camera - screenspace 2d otho menu.
Can I render them consistently in one RTT (for future postprocessing)?
Your terminology is a bit confusing. RTT means render-to-texture. So
what you want is to render to one texture using RTT.
To answer your question: Yes. This is how RTT is used in most of the
cases; Binding a texture to a camera with FBO/Pixelbuffer via RTT and
modifying it. The resulting texture then can be bound to the next camera
etc.
