Alpha over layers but maintain environment background I have a scene where I have a few different render layers that I need to put on top of each other for the final render. Everything works fine when I have transparent background checked for the render but I need to also have the environment background image behind everything. Also, the camera moves and displays different parts of the background, so I can't just alpha over everything on top of an image texture. Is this possible? Thanks in advance!
Enable Environment in the render layers.



Enable Film, transparent.



Then composite your layers with transparency together, and place them over the Environment using Alpha Over.
