Compositor result won't show

Question

I have problem with compositor.

It doesn't show result in output render until I replug Image into Composite node.

I am rendering 2 layers, but it show only first layer, without anything modified, until I unplug and plug back into Image slot in Composite node. Then it shows correctly.

NODE SETUP: enter image description here

EDIT:

Result doesn't show in render output. In Viewer it is visible.

EDIT 2:

Here is the blend file. Sorry for wrong file.

I've had similar behavior. Rendering with F12 seems to work for me as well to 'reboot' the compositor output. I'm new here so I figure I'm missing something. Can't wait to see a good answer. — Chuck, Jan 30 '15 at 13:56
If you don't hit F12 there will be no information for the compositor to work with. — , Jan 30 '15 at 15:02
uhhh. I don't understand. the composite never shows until everything is plugged in. It's like saying "this thing doesn't work when it's off". Did I misunderstand? — ruckus, Jan 30 '15 at 15:27
@Vince Scalia It is plugged in, but doesn't work, until I unplug it and plugit in again or turn off and back on node editor. — Jozef Culen, Jan 30 '15 at 16:21
@cegaton It is not duplicate. I don't have problem previewing. I have problem getting result in render output (F12). — Jozef Culen, Jan 30 '15 at 16:23
I guess I was confused because there are no preview images on the render layer icons (they appear only after you render) in any case I can't reproduce your error http://i.stack.imgur.com/GLM4v.gif — , Jan 30 '15 at 17:07
Thank you. I will upload .blend after weekend. I have it in work. — Jozef Culen, Jan 30 '15 at 17:19
Sorry, I have uploaded wrong file. Link should be correct now. — Jozef Culen, Feb 02 '15 at 12:44
in the bottom of the render tab there is "Post processing" contains "compositing" option which should be checked — Chebhou, Feb 02 '15 at 12:52

To enable compositing go to Post processing in the Render tab of the Properties Panel and:

check the Compositing option
uncheck the Sequencer option

this will process the render result through the compositing pipeline if the compositing nodes are enabled.

This is an answer for an old version, but in 3.1 both Compositing and Sequencer options still exist, albeit they are now in Output tab instead of Render tab. In 3.1 there is no need to uncheck Sequencer for Compositing to work. – mins Apr 25 '22 at 23:26
