Hello. i have some questions:
1) i added another a geometry to the deferred rendering pipeline's Geode object. the geometry doesn't contain texture coordinates but i added color data to it to have a black geometry in the final screen.
the problem is when i rotate the camera the geometry's color gets changed. i don't want that. i guess FG performs some pixel shader or lighting on my geometry. how can i disable that? actually i want a complete black geometry.
2) how can i change FlightGear's background color?
Thank you.
