How can i exclude rendering an enviroment texture in cycles but keeping all the other settings? How can i exclude rendering an enviroment texture in Cycles but keeping all the lighting and reflections that i get from it? like, rendering with the background, but make it black (not transparent)

Already tried to render it as PNG Transparent and then in After Effects add a black background, but what i want is to directly render it on JPEG format with black background to save render time.
Finally what it worked was:


Unchecking the 'Transparent' option before anything
Checking 'Use Enviroment' at the Scene Tab
Most importantly, in the World Tab, uncheck 'Camera'


So with those options the objects will be affected with the background but the background itself will not appear as part of the render.
