How to render All layers in my Compositor at once I have a node grid that renders and adds 10 different layers together. I have added a composition node in the end of the node grid. Though when i Render (F12) it seems like only one of the layers in the composition is rerendered and the other nodes are just applied without rerendering. How can I make all nodes rerender when hitting Render(F12)?

Sorry if my question is unclear, I am a Blender beginner so find it hard to explain my problem.

Any help appreciated! Thanks! :)



Currently I have to press each "green-render-button" (marked in image) to finally get the complete result. I would like to be able to just press Render (marked in orange) and have them all rendered into final image.

Obviously there is something I don't understand because I can't make sense out of it...
You selected Only render the active layer option in the Render layers list. 



With this option only currently selected render layer (active one) will be rendered while others won't be; thus while compositing you'll see new results only on this active render layer.
From manual:


  Using Render Layers can save you from having to re-render your entire image each time you change something, allowing you to instead re-render only the layer(s) that you need.


Deactivate this option and all the Render layers will be rendered again when you press F12 (or with any other way).
